Volkswagen s EA390 engine is good with EA888, advantages and disadvantages.

Shanghai VolkswagenThere are many series, mainly EA211 and EA888 enginesThe EA211 has, and the EA888 has 888 points, and the EA888 is good in Volkswagen.

The technology is not the same.

Shanghai Volkswagen and the main assembly Santana.

Lavida, Langjing, Langxing, Touran, etc., EA888 and the main assembly Tiguan, Passat.

Under normal circumstances, the cylinder block is basically imported, the cylinder head is domestic, and now EA211 is all-aluminum.

Choice of engine.

The power of the car will directly determine the 100 kilometers of the car acceleration time, acceleration time, maximum climbing, the engine power indicators mainly include the maximum power, maximum torque, speed, etc., generally speaking, the maximum power p, the maximum torque t is larger, the stronger the power of the engine, but in fact, this statement is more one-sided.

The power and torque of the engine are not at the same time, and although the maximum torque and maximum power of the two engines are almost the same, the maximum torque point speed and maximum power point speed in the right figure are more close, so the performance in the right picture is better.

EA211 is.

EA888 must be good in terms of displacement, but the oil burning, the oil leakage seems to be similar, EA888 is more serious, especially the first and second generations, the third generation of burning engine oil is slightly better, but the oil leakage continues.

The EA888 engine has two displacements with different powers, with a maximum power of 118kW (160ps) - 5000-6200rpm and a maximum torque of 250Nm - 1500-4500rpm; The maximum power can reach 147kw (200ps) - 5100-6000rpm, and the maximum torque is 280nm - 1700-5000rpm.

The length of the connecting rod of the crankshaft and the piston of the two displacement engines is different, the connecting rod is shorter, and the radius of the crankshaft is larger, in order to increase the exhaust volume. The top structure of the piston is also different between the two, in order to adjust the working volume of the combustion chamber and achieve the same combustion effect.

Technical characteristics of the 88 engine.

The purpose of the vane hydraulic regulator located in the intake camshaft is to effectively improve the intake and exhaust efficiency; Sufficient injection pressure to achieve the most critical part of direct injection in the cylinder; The water-cooled turbocharging technology is used to reduce the volume and weight of redundant parts to a certain extent, making this system relatively stable and reliable;

By controlling the intake manifold flap, the purpose is to meet the charging needs of the engine under different working conditions and improve the output power of the engine; Variable displacement oil pump is used to effectively regulate oil pressure; The use of double counter-rotating balancer shafts is designed to enhance engine balance and reduce noise.

Volkswagen EA888 engine"It is a newly designed engine designed by Volkswagen, which integrates a series of advanced technologies such as in-cylinder direct injection, turbocharging, and variable valve timing, to achieve power, economy and environmental protection.

After reading the shortcomings of the Volkswagen EA888 engine, I didn't dare to buy a Volkswagen.

Volkswagen's characteristic burn-in oil leak!! Reliability issues have to be counted by themselves.

The advantages of EA888 engine include low-speed output, compact structure, increased stability, good silent effect, and reasonable position of the balance shaft; The disadvantage is that the phenomenon of burning engine oil is obvious. Advantage: Low-speed output:

The EA888 can inject fuel directly into the engine with great precision, so that the gasoline can be fully burned and burned for more power. It has the characteristics of low-speed output and fuel saving. Compact structure:

The intake manifold is arranged in the opposite direction, which reduces the length of the exhaust pipe and makes the overall structure more compact. Increased stability: The use of water-cooled turbocharging technology can shorten the volume of parts and components, which can improve the stability of the car.

Good silent effect: The silent timing chain design is adopted, which does not need to be checked and replaced frequently, and the mute effect is better. Reasonable balance shaft position:

The centrifugal force generated by the crankshaft and chain drive is exactly the opposite of the centrifugal force generated by the crankshaft, which can filter out part of the vibration during driving and make the driving more stable. Disadvantages: The phenomenon of rotten burial and burning oil in some models is obvious.

Summary. This engine can be regarded as the king of Volkswagen, and the technology is very advanced. This new engine performs better and consumes less fuel.

And it is also equipped with more black technology, in addition to meeting the user's demand for reducing fuel consumption, but also to meet the exhaust emission requirements of all markets. So as a new engine to replace the EA837, the EA839 uses an aluminum block, FSI-gasoline direct injection engine, with a demand-adjusted high-pressure system and a low-pressure system, and a double overhead camshaft valve control mechanism with four valves per cylinder. And, thanks to the increased cylinder spacing from 90 to 93 mm, a cast cylinder wall cooling system is possible, resulting in a 20 °C cooler cylinder wall temperature compared to EA837 series engines

How do you rate the Volkswagen EA839 engine?

Hello, I'm helping you sort out the answers to your questions, please wait a while This engine can be regarded as the king of Volkswagen, and the technology is very advanced. This new engine performs better and consumes less fuel. And it is also equipped with more black technology, in addition to meeting the user's demand for reducing fuel consumption, but also to meet the exhaust emission requirements of all markets.

So as a new engine to replace the EA837, the EA839 uses an aluminum block, FSI-gasoline direct injection engine, with a demand-adjusted high-pressure system and a low-pressure system, and a double overhead camshaft guess clever valve control mechanism with four valves per cylinder. In addition, since the cylinder spacing has been increased from 90 to 93 mm, the cooling system of the cylinder wall can be cast, so that the temperature of the cylinder wall is 20 °C lower than that of the EA837 series engines

Volkswagen's fourth-generation EA888 engine is still very poor in terms of quality performance, the main problem is that the vehicle's timing system is prone to problems, followed by easy to burn oil and leakage, must be pure to buy carefully.
