Engine Volkswagen EA111 CFNA/CFNB

The Polo 1.6 16V engine has the factory name CFNA. It is a gasoline, four-stroke, 4-cylinder, in-line, 16-valve, with two camshafts. It stands transversely under the hood. The engine has a system of stepless variable valve timing of the intake valves, which makes it flexible in all operating ranges. The engine has a contactless ignition system with four coils. The entire operation of the power unit is controlled by an electronic control unit. Continue reading Engine Volkswagen EA111 CFNA/CFNB

Engine Mercedes M111 E23/E23 ML

In 1995, the last and most voluminous engine in the M111 line of engines came out – this is a 2.3-liter M111 E23 engine. It was intended to replace the completely outdated M102 E23 engine technology. At the heart of the E23 is a cast iron cylinder block, with a bore of 90.9 mm, the piston stroke was increased to 88.4 mm, which is 7.9 mm more than in the 2.0-liter version. Continue reading Engine Mercedes M111 E23/E23 ML

Engine Volkswagen EA113 1.8T

Before us is a modified version of the well-known naturally aspirated 1.8-liter four-cylinder VW engine, the main innovation of which was the use of turbocharging. The cylinder head in the engine uses a 20-valve, 5 valves per cylinder, with a variable valve timing system on the intake shaft. There are hydraulic lifters so you don’t need to adjust the valves to 1.8T. The timing belt uses a belt, which should be changed every ~ 60,000 km; if the belt breaks, the motor will bend the valve.

Engine Volkswagen EA827/EA113 1.8

The EA113 1.8 engine of the Volkswagen EA827 segment was released in 1983. This engine was produced in both carburetor and injection versions. In addition to the differences in the injection system, the EA113 1.8 internal combustion engine had a turbocharged and atmospheric version. The turbine appeared on this engine in 1994. The increase in engine power served to increase the demand for the cars where it was installed. Continue reading Engine Volkswagen EA827/EA113 1.8

Engine Volkswagen EA111 1.2 TSI / TFSI

The 1.2 TSI engine is a representative of the EA111 segment in many ways resembles the 1.4 TSI. However, the main distinguishing feature is the cylinder head modification. The 1.2 TSI version has an aluminum cylinder block with wet cast iron liners. The diameter of the piston group has been reduced to 71 mm (originally this figure was 76.5 mm). Continue reading Engine Volkswagen EA111 1.2 TSI / TFSI

Engine Volkswagen EA113 2.0 TFSI

The two-liter engine of the EA113 TFSI series was released in 2004 and was developed on the basis of a naturally aspirated engine with direct fuel injection VW 2.0 FSI. The main difference between the two engines is not difficult to guess from the first letter added – the new engine is turbocharged. This is not the only difference, the power unit must be properly prepared for high power, instead of an aluminum cylinder block, the TFSI uses a cast-iron cylinder block with a modified balancing mechanism with two balancing shafts, uses a different crankshaft with thick persistent tides, pistons modified for a reduced Compression ratio on reinforced connecting rods.

Engine Volkswagen EA111 1.4 TSI TFSI

The turbocharged internal combustion engines of the EA111 model (1.2 TSI, 1.4l TSI) began to be installed on the cars of the VAG concern back in 2005. These internal combustion engines have a wide range of various modifications, and have replaced 2.0-liter four-cylinder aspirated engines. The very first engine in this lineup was a 1.4l TSI turbocharged internal combustion engine. Continue reading Engine Volkswagen EA111 1.4 TSI TFSI

Engine Volkswagen EA211 1.2 TSI TFSI

In 2012, one of the most popular engines of the VAG EA111 line (1.2l TSI, 1.4l TSI) was replaced by a completely new EA211 engine. The cylinder head (cylinder head) in the new engine series is rotated 180°, which results in the outlet manifold being integrated into the cylinder head and located at the rear. The timing drive was equipped with a toothed belt instead of a chain – now the timing kit is being replaced as planned by 80-90 thousand km. and is less financially costly. The cylinder block itself is made of aluminum alloy, but with cast iron liners. Continue reading Engine Volkswagen EA211 1.2 TSI TFSI

Engine Volkswagen EA211 1.4 TSI TFSI

The 1.4 TSI engines of the EA211 series are equipped with a turbocharging system paired with an intercooler, which is installed in the intake manifold. Depending on the engine modification, different types of turbines are installed. The main advantage of the new series over the old one is the lower weight of the internal combustion engine and more economical fuel consumption. Continue reading Engine Volkswagen EA211 1.4 TSI TFSI

Engine Volkswagen EA827 1.6

The EA827 1.6L engine was developed back in 1985. It was a block with a short-stroke crankshaft of 77.4mm and cylinder diameters of 81mm. Engine with one camshaft and eight valves in the cylinder head (SOHC 8V). The engine versions with injection technology on the intake shaft were equipped with a variable valve timing system. Adjustment of valve clearances on this engine is not necessary, because there are hydraulic compensators in the motor design. Continue reading Engine Volkswagen EA827 1.6
