Q:How much engine oil pressure is normal?

1, oil pressure is too low, will damage the engine lubrication conditions, causing lubrication, cooling and poor cleaning, will cause parts adhesion, wear and tear. The crankshaft spindle neck and connecting rod journal and bearing clearance is too large, oil viscosity is too low and the filter breakdown will cause oil pressure is too low.

Q:What is the power of the engine?

Give a popular example, for example, like a person's body in motion, power is like the durability of the body, and torque is the body's explosive force.

Q:Why a lot of sports car engine is rear?

To the market only RR car Porsche 911, for example, the official announcement of the car before and after the weight ratio is 39:61, almost equal to a reverse of the FF car, and MR car weight ratio is more uniform, Porsche Boxster 46: 54, Ferrari 360 Modena is 43:57. Although some depots appreciate the FR car can do 50:50 car weight ratio, control is also more handy, but from the accelerated point of view, or the first light weight of the MR and RR the most favorable, for the weight ratio before and after Possibly small, the sports car will use the head narrow tail width of the body design and the use of relatively thick rear wheels.

Q:Who invented the jet engine?

Q:What is engine drag braking?

If at this time the direct use of drag block mode to realize deceleration, then there will be a driver hand control lever, a hand holding the steering wheel of the new situation, many inexperienced drivers at this time will care for this and lose that ability to cope with unexpected events, large decline, anti had created a traffic safety hazard. At the same time, when the car slows down, it also needs to remind the back of the vehicle, which requires the driver to step on the brake board so that the brake light is on. Otherwise, in the case of not stepping down the brake pedal, forcibly pull the gear, slow down the car, the vehicle does not follow the driving situation behind, it is prone to traffic accidents

Q:Car engines: what does V12 mean?

Displacement of about 4 liters of the engine is generally 8 cylinder, such as displacement of 4.7 liters of Beijing jeep JEEP4700. Displacement of more than 5.5 liters of engines in general use 12 cylinder engines, such as displacement of 6 liters of BMW 760Li, use V12 engine. In the same cylinder size, usually cylinder number larger displacement, the power is high; and in the capacity of the engine under the same cylinder number, diameter is smaller, the engine speed can be improved, so as to get bigger promotion power.

Q:The principle of automobile engine

(2) splash lubrication: the use of the engine when working with some moving parts (mainly crankshaft and camshaft) splashing oil droplets and oil mist, the friction surface of a way of lubrication.

Q:What is the driving function of the brake and the engine? What do they mean?

3) second brake system - a set of devices that ensure that the car can still slow down or stop when the train brake system fails. Second brake system is also necessary for the car. Also called emergency brake and safety brake.

Q:Advantages and disadvantages of CVVT engines

Disadvantages: only control valve timing, there is no control valve lift function. Therefore, the engine will only change the suction and exhaust time difference, can not change the intake.

Q:What is the TSI engine?

The supercharger has the advantages of engine starting operation began to intervene, accelerate strong, no turbine work delay, immediate response, the disadvantage is through the power of the engine output for turbocharger, consume part of the power of the engine.
