Is EA888 engine direct injection or mixed injection better, which is more fuel efficient?

In fact, this is not absolute, in general: avoid engine idling for a long time, and avoid sudden braking as much as possible. Use the high and low gears reasonably and maintain the appropriate driving speed.

In general, driving speeds are most fuel-efficient at kilometres per hour, increasing fuel consumption by 15% at speeds of 105 km/h and by 25% at 110 to 120 km/h. Keep the vehicle low in wind resistance, try not to load on the roof, or make unreasonable modifications.

Do a good job of daily maintenance. Unclean air and oil filters, worn spark plugs, and problematic emission control systems can all increase fuel consumption. According to statistics, it is normal for a poorly maintained engine to increase fuel consumption by 10% or 20%, and an air filter that is too dirty can also lead to a 10% increase in fuel consumption.

In order to maintain the optimal performance of the car, it is best to change the oil every 5000 kilometers and check the filter, which is also important for the maintenance of the car. If the tire pressure is not enough to maintain a normal tire pressure level, the rolling resistance will increase significantly. Reducing the burden on the car and cleaning up unnecessary things in the trunk can reduce the weight of the car and also achieve the effect of energy saving.

Choose a reasonable access route. When stuck in traffic, the fuel consumption of the car is the maximum.

It's time to use it! Personally, I think the direct injection is tear-resistant!

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.

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

Advantages: In-cylinder direct injection: Mercedes-Benz has also had in-cylinder direct injection, but only Volkswagen and Audi are proficient in using in-cylinder Mofengchun direct injection technology.

In the past, the Volkswagen engine first mixed oil and gas in the intake pipe and then injected into the engine for combustion, but the new generation Volkswagen EA888 is very precise to inject fuel directly into the engine, so that the gasoline can be fully burned and obtain higher power. At the same time, it has a low blind speed output, saving 15% of fuel.

2.The third-generation EA888 engine adopts a forward and reverse intake manifold layout, which reduces the length of the exhaust pipe and makes the overall structure more compact.

3.Water-cooled turbocharging technology, the engine's turbocharging and exhaust pipe are integrated design, which shortens the volume of parts and improves the stability of the car.

4.The silent timing chain is designed with Ki, and the small partner does not need to check and replace the belt frequently, and the mute effect is better.

5.The position of the new balance shaft is more reasonable, and the centrifugal force generated by the crankshaft and chain drive is exactly the opposite of the centrifugal force generated by the crankshaft, so that a little vibration can be filtered out during the driving process, and the drive is smoother.

Disadvantages: Not only the Volkswagen series, but also the Audi series, the engine basically has the same disadvantage: burning engine oil. Although the new generation EA888 has improved somewhat, the burning of engine oil has not been greatly improved.

Millions of car purchase subsidies.

EA888 injects fuel directly into the engine, so that the gasoline can be fully burned, obtain higher power, and at the same time, it has a low speed output, so that the fuel is saved by 15%. The EA888 engine adopts the form of front intake manifold and reverse layout, which shortens the length of the exhaust pipe and makes the overall structure more compact.

Speaking of Haval H5 as a flagship model of Haval, from the perspective of the structure of the vehicle, it has the appearance of the Haval series and the atmosphere of the Haval family, as a Haval H5 focusing on the low-end market, why is it different from the EA888 engine? The engine used in the Haval H5 is a Mitsubishi engine, and this engine is also a main engine of Mitsubishi before.

Judging from the current technology, although this engine is not as powerful as the first technology, the overall effect is still good, although the Mitsubishi engine is used, why not use EA888? EA888 engine is the main engine of Volkswagen, which is mainly used in high-end models such as Volkswagen and Audi.

For Volkswagen, EA888 represents Volkswagen's mainstream technology, once it is given to other manufacturers, it will make the corresponding reverse development between manufacturers, which will have an impact on Volkswagen.

Secondly, from the point of view of engine performance, EA888 as a mainstream engine, has a certain well-known, once Haval H5 is adopted, then how to adjust the power of the vehicle? The choice of engine is not without consideration, on the one hand, the performance of the vehicle, and on the other hand, the overall driving experience.

This is important for Haval (parameter |**) is a problem, but also will face a ** problem, after all, the use of this engine from the top than Mitsubishi's engine is more expensive, then the appropriate will improve the car **, and the silver suspect itself Haval in the market pricing is relatively low, once the new engine is adopted, then ** will be raised, may also be counterproductive.

Great Wall for Haval H5 (parameter |**) should be positioned lower than h6 (parameter |**), once the facelifted engine is used, the sales of the H6 will be cut in half, so the representative model H6, which has always had the power of the Great Wall, will also have a certain decline in sales, which is unwilling to see for the Great Wall. Finally, as an aside, without EA888, in addition to the Great Wall's own technical level, it is also inseparable from the competition between manufacturers.

1: EA888 is Volkswagen and engine. Also includes Skoda and Audi.

This engine requires a number 95, and this engine is squeamish. It is easy to burn engine oil, leak oil and leak oil, as well as oil leakage. The advantage is that it is more energetic.

Fuel efficient. The cost is relatively cheap netizens.

2: H5 is a cheap and practical route, with EA888 engine can only increase the cost, and it is impossible, even if you don't use the current Mitsubishi engine H5 will also use your own 4C20 series of gasoline engines, it is impossible to use Volkswagen's engine, one is high cost, and the other reason is that the reliability of the engine of the Volkswagen factory is particularly good.
