Opel Astra engine, technical characteristics of Opel Astra engines. Opel Astra engine, technical characteristics of Opel Astra engines Maintenance of Opel Esotes engines

Engine Opel Astra n 1.6 liters 115 hp quite a popular power unit in our country. A reliable naturally aspirated engine was developed by German engineers taking into account all modern trends. Inline 4-cylinder 16 valve engine Opel Astra h is an evolution of the Ecotec series. These gasoline units can be found not only on Opel, but also on other models of the global concern General Motors.

An engine that complies with Euro 4 environmental standards is marked Z16XER; if it is a re-flashed engine for Euro 5, then its name is A16XER. Although structurally, these are the same motor. Now let's talk about construction.

Device Opel Astra h 1.6

The basis of the engine design is a cast iron cylinder block. The cylinders are machined directly into the block. The 16-valve mechanism usually does not cause problems, since there are hydraulic compensators and there is no need to adjust the thermal clearance of the valves. The timing belt drive is based on the timing belt. But we’ll talk about the belt drive a little lower. The main feature of the engine can be considered a phase change system on both camshafts. It is this system that causes a lot of trouble. especially if you pour low-quality oil. After all, phase shifters work exclusively due to oil pressure, focusing on various sensors. If you hear a strange rattling sound (diesel sound) from under the hood, then do not rush to blame the hydraulic compensators; most likely it is the actuators of the CVCP variable valve timing system that have failed.

The operation of the CVCP phase change system is shown schematically in the following picture.

Timing device Opel Astra h 1.6

Characteristics of Opel Astra h 1.6 (115 hp)

• Working volume – 1598 cm3
• Number of cylinders – 4
• Number of valves – 16
• Cylinder diameter – 79 mm
• Piston stroke – 81.5 mm
• Timing drive - belt
• Power hp (kW) – 115 (85) at 6000 rpm. per minute
• Torque – 155 Nm at 4000 rpm. per minute
• Maximum speed – 191 km/h
• Acceleration to the first hundred – 11.7 seconds
• Fuel type – gasoline AI-95
• Compression ratio – 10.8
• Fuel consumption in the city – 8.8 liters
• Fuel consumption on the highway – 5.5 liters
• Fuel consumption in the combined cycle – 6.8 liters

With proper and timely maintenance, this power unit can travel for quite a long time, without any problems at all. The engine is assembled at the Opel plant in Hungary in the town of Szentgotthard. The A16XER/Z16XER engine can be found in Opel Astra, Mokka, Insignia and naturally on Chevrolet Cruze(although there it easily produces 124 hp).

Opel engineers have created a special series of ECOTES engines. The goal of the ECOTEC program is to create modern engines internal combustion, which have the following properties and characteristics:

1. High power.
2. Excellent torque.
3. Economical (low fuel and engine oil consumption).
4. Low toxicity of exhaust gases.

Efficiency of Twinport technology

These engine characteristics are successfully combined when equipped with a 4-valve gas distribution. Opel ECOTES engines are equipped with Twinport technology. When used, air enters the cylinders through one intake valve at low engine loads.

The second valve is closed throttle valve. When air enters the cylinders, it forms turbulence in a spiral, leading to improved mixture formation, cooling of the cylinders, and complete combustion of the fuel-air mixture.

The additional damper opens when the load increases. At the same time, the Opel ECOTES engine receives effective filling of the cylinders with additional portions of air.

Thanks to the use of Twinport technologies, the Opel ESOTES engine reduces consumption by 1.6 liters diesel fuel or gasoline by 6%.

Diesel benefits when using Twinport

In diesel power units, the intake valves are located at an angle. In this case, the air flows, when twisted, form the most homogeneous fuel-air mixtures.

The diesel engine fuel pump has direct fuel injection. At the same time, it develops high pressure, equal to 1300 - 1500 atmospheres, the nozzle sprays the fuel in a super finely dispersed form. As a result, the diesel engine receives high-quality mixture formation.

The diesel engine is equipped with one camshaft to control all four valves according to the SONC gas distribution system.

Engine specifications Opel Omega A 2.0 i

The 1998 cm3 engine is located under the hood at the front in a longitudinal view. Four cylinders are placed in a row. The diameter of each cylinder is 86 mm, the number of valves is 2. Power is supplied by a distributed injection system. Developed power - 115 hp. With. The fuel consumed is AI 95 gasoline.

The fuel tank holds 75 liters, fuel consumption depends on operating conditions:

• in the city, in the presence of traffic jams, it is 11.9 - 12.1 liters per 100 km.
• outside the city on the open highway - 6.3 l./100 km.

Any engine in the Opel family is reliable and easy to operate. There is an EGR system - using electronics, exhaust gas recirculation is controlled. In this case, the exhaust gases are fed back into intake manifold and are re-burned in the cylinders. The recirculation system helps reduce fuel consumption and the amount of harmful emissions through the exhaust pipe.

Opel engine markings

The engine markings are located on the cylinder block body in the area of ​​spark plug number 4. The markings differ according to the type of engine - gasoline, diesel.

For example, a power unit with embossed symbols C 20LET:

1. C - catalyst.
2. 20 - engine capacity 2.0.
3. L - compression ratio.
4. E - power system (injector).
5. T - turbine.

Catalysts are characterized by the letters C, X, Z.

Compression ratio - G, L, N, S, X, Y.

Power system - E, Z, V, D.

Opel ESOTES engine maintenance

When carrying out scheduled technical measures, it is necessary to change the timing belt and tension rollers. If signs of belt wear are detected prematurely, it urgently needs to be replaced without waiting for scheduled work.

This is caused by serious damage that the motor receives when this unit breaks.

Serious attention is paid to the EGR valve for exhaust gas recirculation. If it malfunctions, engine starting and operation deteriorate sharply. Idling becomes unstable.

Opel engine repair

Despite the reliability of the line power units OREL company, the motor requires regular diagnostics, adjustment and repair of systems, components and parts.

The most common problems include the following defects:

1. Damage and wear of the drive belt.
2. Rheostat failure.
3. Depressurization of the cooling system.
4. Oil pump failure.
5. Increasing clearance between pins and connecting rod, resulting in loss of compression.
6. Cylinder detonation.
7. Deformation of the pulley hub, connecting rod.
8. Valve position.
9. Pressure sensor failure.

Defects in the operation of the cylinder-piston group lead to a sharp increase in the consumption of fuels and lubricants, loss of power and compression, and problems when starting the engine.

It is the responsibility of the car owner to adhere to the schedule. In accordance with it, scheduled repairs of the Opel engine are carried out, otherwise the internal combustion engine may receive irreversible defects, after which it will be necessary to completely change it.

Restoration work must be carried out in specialized service centers. Only there you can purchase original certified spare parts for your engine.

Adam Opel AG is a German manufacturer of popular cars in the mid-price segment. Together with sister Vauxhall, Korean Daewoo (GM Korea), Australian Holden, Swedish SAAB and American companies Chevrolet, Cadillac, GMC and Buick, the German manufacturer is part of a well-known General concern Motors. Most of the cars of these manufacturers are quite seriously unified and use common components and assemblies, platforms and other developments.

Opel engines and their variations are no exception and are used in one form or another on various cars of the concern.
Opel's engine lineup consists primarily of inline 4-cylinder engines and, more recently, turbocharged fours. Such engines, with a small volume, 1.4, 1.6 turbo, produce quite a lot of power and torque. Larger engines were also produced, with a volume of 1.7, 1.8, 2.0, and a 2.0 turbo was installed on sports versions, like the Astra OPC.
Along with a wide range of in-line fours, Opel engines were also produced in in-line and V6 variations, both turbo and naturally aspirated. There is a family of diesel engines, mostly 4-cylinder.
To understand all this diversity, now you don’t need to look for any reviews; Wikimotors has all the necessary reviews, both new Opel engines and old ones, turbocharged, naturally aspirated and others.
In addition, you will be able to find out specifications, resource, malfunctions (troit, knocking, noise, vibration, etc.), repair of Opel engines, their weight, where the engine number is located, temperature, tuning, etc. One of the most important aspects in operating a car is the choice of oil. WikiMotors has information about what oil is recommended to be poured into an Opel engine, how often the oil needs to be changed and how much to fill.
After reading the articles, you will find out which engine is best for your car, and those who want to replace their engine or buy contract engine Opel will easily figure out what to choose and not make a mistake.

Engine and gearbox Opel Meriva

One of the main advantages of the Opel Meriva engine is its almost silent operation.

While in the cabin with the engine running idle speed engine, it is generally impossible to determine by ear whether it is working or not. You can guess that the machine is still working only by looking at the non-lit battery charging indicator.

And even outside, at low engine speeds, it’s easy to make a mistake and decide that the car has stalled. It is only after approximately 3000 rpm that the engine noise becomes clearly audible.

At the same time, the engine provides excellent dynamics.

Even with the interior and trunk fully loaded, acceleration is very easy. Moreover, even with an engine capacity of 1.6 liters.

And there’s no need to even talk about the two-liter one. At the same time, even the turned on air conditioner does not have a big impact on the dynamics - the car easily accelerates to 160 km/h. The only factor that negatively affects the dynamics is the fairly decent height of the car, which is 1.6 m. By the way, it is precisely because of the height, which gives increased windage, that the car, when reaching a certain speed, begins to feel a side wind. However, the car is not intended for high-speed racing, so this minus can be forgiven to its developers.

A positive point is the efficiency of the engine, which consumes a small amount of fuel.

In the urban cycle, consumption is about 9 liters per 100 kilometers. on the highway an average of 7 - 7.5 liters.

The gearbox works, one might say, flawlessly.

If we exclude the point that sometimes, for example, after third speed it is difficult to turn on the first one - which is not surprising - then it is generally ideal.

The inclusion of reverse speed is implemented correctly. You can't just turn it on. First you need to lift up a special safety ring. This eliminates the involuntary engagement of reverse gear.

To all this you can also add excellent sound insulation of the car interior. The noise of the wheels becomes audible only when the speed exceeds 100 km/h.

Opel Vectra A engine markings

Due to frequently asked questions– what engine and beam do I have? I decided to clarify a little for all owners of the Opel Vectra A. And so, let's start with where to find the markings on the engine itself, what it might look like, and how to decipher it correctly. Basically, the engine markings are stamped on one of the small stems of the block, most often near the 4th spark plug. For those who do not know the correct order for marking candles, I tell you that the numbering goes from left to right.

I would also like to note that some engines of the same marking are both PRE-STYLE and RESTYLE, the differences of which lie in an improved and more reliable design. For example, if you take an engine marked C20NE. in a pre-restyled engine, the generator, power steering pump and pulley go under a V-belt, and in a restyled engine under a traction belt. As practice and experience show, a restyled engine is more reliable in that the spare parts for the ridge belt are more reliable and durable, and accordingly last much longer.

Now I will give below an approximate diagram of gasoline and diesel engines that were installed on Opel Vectra A in the period from 1988 to 1995.

Gasoline engine markings:

• Marking (14NVH)– volume (1389 cc) – hp (75) year of manufacture (9/1993-10/1995)
• Marking (16SV)– volume (1598 cc) – hp (82) year of manufacture (9/1988-5/1993
• Marking (C16NZ)– volume (1598 cc) – hp (75) year of manufacture (9/1988-10/1995
• Marking (E16NZ)– volume (1598 cc) – hp (75) year of manufacture (9/1988-10/1990
• Marking (X16SZ)– volume (1598 cc) – hp (71) year of manufacture (9/1993-10/1995
• Marking (18SV)– volume (1796 cc) – hp (90) year of manufacture (9/1989-10/1990
• Marking (C18NZ)– volume (1796 cc) – hp (90) year of manufacture (3/1990-10/1995
• Marking (E18NVR)– volume (1796 cc) – hp (88) year of manufacture (9/1988-7/1989
• Marking (20NE)– volume (1998 cc) – hp (115) year of manufacture (9/1988-10/1990
• Marking (20SEH)– volume (1998 cc) – hp (129) year of manufacture (10/1988-9/1992
• Marking (C20NE)– volume (1998 cc) – hp (115) year of manufacture (9/1988-10/1995
• Marking (20XEJ)– volume (1998 cc) – hp (150) year of manufacture (1/1989-6/1994 4V
• Marking (C20XE)– volume (1998 cc) – hp (150) year of manufacture (2/1990-10/1995 4V
• Marking (X20XEV)– volume (1998 cc) – hp (136) year of manufacture (6/1994-10/1995 4V
• Marking (C20LET)– volume (1998 cc) – hp (204) year of manufacture (6/1994-10/1995 4V
• Marking (X25XE)– volume (2498 cc) – hp (170) year of manufacture (2/1993-11/1995 4V

Marking diesel engines:

• Marking (17D)– volume (1699 cc) – hp (57) year of manufacture (10/1988-9/1992
• Marking (17DR)– volume (1699 cc) – hp (60) year of manufacture (7/1992-10/1995
• Marking (17DT)– volume (1686 cc) – hp (82) year of manufacture (3/1990-11/1995 (Isuzu)
• Marking (X17DT)– volume (1686 cc) – hp (82) year of manufacture (3/1990-10/1995 (Isuzu TC4EE1)

How to correctly decipher the engine index:

For example, let's take the most strong engine according to indications, this C 2 0 L E T. The first letter (C) means the presence of a catalyst, followed by numbers (20) - this indicates the engine size, i.e. 2.0. The next letter (L) immediately after the numbers indicates the compression ratio, in our case it is 8.5. The letter (E) means the type of power system, in our case it is a multipoint power system, in other words, a full injector. Well, the last letter (T) means the presence of a Turbine.

The following diagram comes out:

And finally, the keys themselves for decoding the engine.

1 – compliance with environmental standards (for cars with a neutralizer)

• C – Catalyst (exhaust complies with 83 standards (ECE R83A)
• X – Catalyst (exhaust complies with 94 standards (94/12/EC)
• X (for diesel) – No catalyst (exhaust meets ’94 standards
• Z – Emission rate higher than X

2 and 3 – working volume (20 - 2.0 l, etc.)

4 – compression degree designation:

• G – no more than 8.5
• L – within 8.5 – 9.0
• N – within 9.0 – 9.5
• S – within 9.5 – 10.0
• X – within 10.0 – 11.5
• Y – more than 11.5

5 – type of power system:

• E - multipoint (distributed) injection;
• Z - single injection;
• V - carburetor;
• D - diesel

6 – engine options

• T - turbine
• L - low
• V - average-nominal-optimal
• R- increased
• H-high
• J - maximum

Engine Opel Astra, which is installed on Russian version The car is mostly petrol, naturally aspirated, from the EcoTec series. Of course, there are turbo versions and even diesel ones. It just so happens that in our country today two generations of Opel Astra are being sold simultaneously. Current “J” and previous “H”, called Family. The engines of the two generations of cars differ only in the settings that determine the environmental standard. The new generation of engines complies with Euro-5 (A), the old generation of engines complies with Euro-4 (Z).

Today we will tell you in detail about the main engines of the Opel Astra. These are time-tested naturally aspirated gasoline engines with a displacement of 1.6, 1.8 and new turbo engines with a displacement of 1.4 and 1.6 liters.

Petrol naturally aspirated engine Opel Astra Z16XER(Euro-4) and A16XER (Euro-5) is an in-line 4-cylinder 16-valve power unit with a cast iron cylinder block. The cylinder head is made of aluminum alloy. The cylinder head contains two camshafts, which open the intake and exhaust valves. Valve pushers simultaneously serve as hydraulic compensators. Thus, there is no need to adjust the valve clearance; this happens automatically, using the hydraulic compensators of the Opel Astra 1.6 engine.

Engine Astra 1.6 It is also equipped with a variable valve timing system (VVT) on both camshafts. As for the timing drive, the synchronized rotation of the crankshaft with the camshafts is ensured by the belt. Timing belt The Opel Astra engine is quite durable and easily lasts for more than 100 thousand kilometers. The power system uses distributed fuel injection. Below are the engine characteristics.
