Q:What are the criteria for judging the performance of an automobile engine?: The 4. rear engine, rear wheel drive (RR): it seems to be a facelift of the FF car, just in front of the car after the shift to "the viscera". The vehicle retains the advantages of FF bus, FF also eliminates the shortcomings of the car, because the car layout more reasonable, and the noise and improve the temperature inside the car, with its unique structure and good performance by the users.

Q:Why some engine exhaust pipe in front, some are in the back! What are the advantages and disadvantages: Only the tapping engine only "positive and negative" that the longitudinal engine into the exhaust manifold at both ends, the exchange is no difference, so there is no such argument.

Q:What is the role of the engine timing belt?: Timing, that is, through the engine timing mechanism, so that each cylinder just to do: the piston just up to the top dead center, the valve just closed, spark plug just ignition.

Q:What is the 4GB2 engine?: The new and 1.5L VVT (4GB2 power) is JAC joint international renowned research institutions, the integration of the world advanced power technology research and development resources, a new generation of aluminum 1.5L VVT small displacement engine together with the international first-class R & D manufacturing, international leading technology. Based on the international leading technology of MITSUBISHI 4A91 platform optimization design, for the upgrading of MITSUBISHI 4G15 technology version of the perfect presentation. The perfect presentation of the six major performance improvements:

Q:What is the material of the engine valve, especially the exhaust valve?: The exhaust valve consists of three parts of the materials, the head is 21 4N austenitic materials by solid solution and aging treatment, the grain size of 6 - 9, the hardness more than 30HRC, can work for a long time at 850 degrees Celsius; head cone surface welding of cobalt base alloy STELLITE F, has very strong corrosion resistance at high temperature. Next, the impact resistance and high creep strength, the service life is crucial; rod material is 4Cr9Si2, heat treatment by quenching and tempering, the grain size of 10 - 12, 30 - 40HRC in hardness

Q:On the car engine under the shield, made Han material good? To discuss the next: There are many people repeatedly stressed that this light shield can not play a protective role

Q:Aircraft engine spray blue fire and red color of the fire, what is the difference between the two?: Visible photons are enhanced in the order of red orange, yellow, green and blue.

Q:What about the BYD F3 engine?: BYDF3 is the use of aluminum engine (actually just shell), can reduce the body weight, the high number of parameters, compared with the previous Dongan MITSUBISHI 4G15S engine, now at a lower speed can achieve higher peak torque, power is stronger.

Q:What are the six engines?: But usually we have "four matching", is actually in the cylinder (engine bottom) internal parts, such as cylinder, piston, piston ring, bearing, commonly known as the "four support", this usually is usually used in the engine overhaul use "NOUN

Q:The new Regal 2.0T engine and MAGOTAN 2.0T engine which is better?: First look at the data of the new Regal 2.0T maximum power 162kw/5300rpm, maximum torque 350Nm/2000-4000rpm MAGOTAN 2.0T maximum power 147kW/6000rpm, maximum torque of 280Nm/1800-5000rpm, GDI technology new Regal 2.0T dual-mode gasoline direct injection SIDI, using stratified combustion mode and homogeneous combustion mode (not MAGOTAN 2.0TSI Audi TFSI), just the basic cylinder straight the jet technology and material Regal 2.0T is double VVT, the Aluminum Alloy MAGOTAN 2.0T, no VVT is the ease of use of cast iron
