What are the advantages and disadvantages of the Duratec-HE all-aluminum alloy inversion engine?

1. The Duratec-HE engine has the following characteristics: aluminum alloy material, which is lighter than the same displacement engine. 18 reverse design (forward rear row), and increase the angle of the intake valve and exhaust valve to greatly improve engine efficiency.

2. Duratec HE adopts this unique inversion engine design. Its biggest advantage is that it can improve the cooling effect of the intake manifold, increase the oxygen content of the air entering the cylinder, and greatly increase the combustion efficiency.

3. The Duratec-HE reverse all-aluminum alloy engine is cast with all-aluminum alloy material, and Cosworth technology, which is famous for developing F1 racing power, is specially introduced. The unique inversion design can greatly improve combustion efficiency and reduce fuel consumption and exhaust emissions.

4. The Focus Duratec-HE all-aluminum alloy reverse engine is equipped with a plastic steel isolong intake manifold and a variable inertial intake system (VIS), which can ensure the continuous and stable power of the engine in various situations.

5. Focus is equipped with Duratec-HE all-aluminum alloy inversion engines 8L and 0L, which are cast in lightweight all-aluminum alloy with a unique inversion design.

Classification of engine layout

1. Generally speaking, the purest rear engine is to arrange the engine behind the rear axle. The most representative is the bus, and there are only a few passenger cars with rear engine. The most representative is the Porsche 911, of course Smart is also a rear engine.

2. The layout of the engine on the car is actually closely related to the performance of the car. The general layout is divided into front, middle and rear. The most common of the cars we use in daily use is the front layout, and the front layout is divided into horizontal and vertical. The simplest judgment method is It was a man standing in front of the car and opening the engine cover.

3. Most sports cars are four-wheel drive or rear-wheel drive, and rear-wheel drive sports cars are faster.

4. W-type engine The W-type engine is not a cylinder arranged in a W-shape, but a group of V-type engines formed by two sets of VR engines arranged according to the V-type engine.

5. Engine front-rear-wheel drive (FR): Front-engine Rear-drive · Features: It is a traditional layout form, which is adopted by most trucks, some cars and buses.

Why is the idle speed of the Fox unstable~

The unstable idle speed is: when idling, the engine trembles and the speed is uneven. The causes are: blockage of the idle air measuring hole, poor operation of the idle device, weak sparks of individual cylinder spark plugs, loose sealing of individual valves, leakage of air intake manifolds, too early or too late ignition time, improper idling adjustment, etc.

This problem is basically caused by the carbonization of the throttle valve, and the main cause of the carbonization of the throttle valve is caused by the use of a reverse engine by the Focus. It is easy to accumulate carbon due to the frequent use of walking and stopping in normal cities or the use of low-speed gear shifting due to fuel consumption and noise.

Engine parts aging: turning on the electrical system of the engine in the idle state will increase the load of the engine, causing the engine to automatically increase the speed; unstable oil pressure: the oil supply pressure of the oil pump is abnormal or the intake pressure sensor is numerically incorrect and does not work.

Why is the BMW 310r engine reversed

1. Due to the reverse engine, the center of gravity is more concentrated and the control is more flexible It is lightweight and burden-free, almost like riding 150cc. How is the power performance? In terms of power, the single-cylinder is the only way. The acceleration is within the acceptable range, and the shock suppression effect is also good compared with other single-cylinder cars. The single-cylinder speed increase is very fast. It will not be delayed until 120.

2. The G310R is the first small-displacement model launched by BMW. Although the equipment is not particularly prominent, the signboard of the Bavarian engine and the special reverse engine still caused quite a sensation that year.However, the main purpose of exploring the launch of the G310 series is, of course, to attract new users who have never been BMW Riders.

3. The series may be the most controversial product of BMW motorcycles in China. The high price, low cost performance, and small problems in the early stage have more or less had a negative impact on the reputation and reputation.

4. BMW G 310 R and G 310 GS are BMW's entry-level motorcycles and the only motorcycles completely manufactured by India. There are BS6 versions of these two cars, which were supposed to be released earlier this year, but the relevant plans were put on hold due to the Covid-19 pandemic.

The speed of Jianghuai Kangling truck exceeds 80, the engine fault light is on, and then it drops to 2000 rpm, and the speed cannot exceed...

Hello, first of all, the fault light is on, which proves that the engine electronic control system does have a fault, and the fault code is remembered. Secondly, the normal idling speed is about 800 rpm, and Your car has only run more than 20,000 yuan, so there are two conclusions: 1. The idle solenoid valve is damaged and the idle speed cannot be adjusted, so the idle speed is high.

First of all, fuel consumption is related to the displacement of your car. Secondly, the factors affecting fuel consumption have a lot to do with your personal driving habits and driving conditions, especially the impact of road conditions, and the fuel consumption in urban areas is relatively high.

The quality of automobile fuel is not qualified. If the vehicle is refueled shortly after it is refueled, the dashboard of the carThe engine fault light above is on. Well, this is generally because the oil is added incorrectly, the quality is poor, and it does not meet the standard, resulting in insufficient combustion of the oil and gas mixture when the engine is working.

Hello, you need to go to the repair shop to read the specific fault code with a decoder, and then repair it according to the fault code. Thank you for using it. I hope my answer can help you. It would be great if it could help you. The car master specializes in serving car owners. I hope it can help you. Thank you for using it again.

Lift the clutch to drive normally to 40 yards, about 2 gears 2000 rpm, step on the clutch and hang the gear. Because the driver's hand speed is too slow, after pulling into the third gear, the engine drops to idle speed (800 rpm). At this time, lift the clutch, the engine is docked with the tire. Due to the mismatch of speed, the engine is pulled by the tire speed. 1300 returns.

How about Geely 1.5t four-cylinder engine

1, how about Geely 5t four-cylinder engine? According to the data, the maximum horsepower of Geely's new 5T engine reaches 181Ps, and the maximum torque is expected to reach 290N·m.

2. The maximum power of the Boyue l5t engine is 110kW, the maximum torque is 225Nm, and the net power is 108kW.

3. The power performance is good. The 5T four-cylinder turbocharged engine does not need to worry about the jitter of the three-cylinder. The power output of 181 horsepower is also excellent, and the push-back feeling is strong.

4. In fact, Geely Binyue has always performed very well in the domestic small SUV market, that isPreviously, the three-cylinder power of 5T was adopted, but also because of its excellent power performance and overall good texture, it has won the recognition of some users. It has been regarded as a model with good performance in the domestic three-cylinder engine.
