This inline 4-cylinder engine with cast iron cylinder block and injector power system combines reliability and economy, making it a popular choice for models such as the Opel Astra, Opel Mokka and Opel Insignia.
Specifications
With a cylinder bore of 79 mm and a piston stroke of 81.5 mm, the engine has a displacement of 1,598 cc. The compression ratio is 10.8, which contributes to efficient combustion and maximum power of 115 hp at 6,000 rpm. The engine torque reaches 155 Nm at 4000 rpm, which provides good acceleration dynamics and confident driving in various operating modes.
The fuel system is designed to use 95 grade gasoline, which meets the requirements of Euro 4 and Euro 5 environmental standards. Fuel consumption in urban conditions is 8.3 liters per 100 km, on the highway – 5.1 liters, and in the mixed cycle – 6.3 liters per 100 km. This makes the engine quite economical, which is especially important for everyday use.
To maintain optimal engine performance it is recommended to use oils with viscosity 5W-30, 5W-40, and for areas with low temperatures – 0W-30 or 0W-40. The volume of oil in the engine is 4.5 liters, and it is recommended to fill from 4 to 4.5 liters when changing the oil. Oil change intervals are 15000 km, and in conditions of urban operation – 7500 km.
Although the exact life of the engine according to the factory is not specified, in practice it is from 200 to 250 thousand kilometers. At the same time, the engine demonstrates high reliability and stability in operation, which is confirmed by numerous reviews of owners.
As for tuning, the engine Z16XER / A16XER has the potential to increase power up to 130 hp without significant loss of resource. However, more serious modifications require additional study and tuning.
Overall, the Z16XER / A16XER engine is an excellent example of the combination of reliability, economy and tuning capabilities that make it a popular choice for many Opel models.
Characteristics of the Z16XER / A16XER engine
Z16XER (A16XER) engine troubleshooting and repair
The A16XER engine is a popular and time-tested Opel engine. Originally it had the name Z16XER and was put on the Opel Astra H.
The current A16XER is a development of the Z16XEP/Z16XE1, which was installed on the cylinder head from the 1.8-liter Z18XER with a system of variable valve timing on two shafts.
The engine is produced in two variations, under the environmental standards Euro-4 and is called Z16XER, under Euro-5 is named A16XER, do not look for a lot of two differences, it is one engine.
Among other things, this engine was produced in South Korea, for a related brand Chevrolet, under the name F16D4 and, accordingly, all the problems are completely repeated.
This motor has a counterpart with a larger displacement and correspondingly higher power – A18XER.
Tuning the engine Opel A16XER
Chip tuning engine A16XER
The usual calibration of the motor will not change the essence of the case, a gain of 5 hp. is difficult to feel, so that your cart fell, you need to put exhaust spider 4-2-1, that removes the catalytic converter, buy a receiver, flashing and get a motor with a more sporty character and power of about 125-130 hp.
Compressor and turbine
This idea is initially not quite adequate, due to the fact that the standard car will require too serious interventions, modification of the suspension, brake system, replacement of the piston group, etc. But if you need something to occupy your hands, then buy a forged CMP under compression ratio of about 8.5, TD04L turbine, intercooler, bypass, manifold, pipes, exhaust build on a pipe 63mm, consumables, roll back online and get your ~200 hp. The price of pleasure is very high.
If not intimidated, then this article describes everything to build your A16XER turbo.
