What is meant by water-cooled inline 4-cylinder, 4-valve electronically controlled multipoint injection gasoline engine?

Water-cooled means that the engine is cooled by cooling water. Inline 4-cylinder refers to the cylinder arrangement form using inline arrangement, inline engine cylinder block in a row, cylinder block, cylinder head and crankshaft structure is simple, low manufacturing cost, low speed torque characteristics, fuel consumption, compact size, more widely used, the disadvantage of the power is lower. 4-valve refers to a cylinder double-row double into *** four valves, engine a *** 16 valves. Electronically controlled multi-point injection system (MPI), is an electronic control device (also known as computer or ECU) for the control center, the use of a variety of sensors installed in different parts of the engine, measured by a variety of operating parameters of the engine, according to the pre-set in the computer in the control program, through the control of the injector, precise control of the amount of fuel injected, so that the engine in a variety of conditions can be obtained under the best concentration of the gas mixture. In addition, the electronic control gasoline injection system through the computer control program, but also to achieve the start-up enrichment, warm-up enrichment, acceleration enrichment, full-load enrichment, deceleration thinning, forced idling fuel cut-off, automatic idling speed control, etc., to meet the special engine conditions on the requirements of the mixture, so that the engine to obtain a good fuel economy and emissions, but also to improve the performance of the car. That's all, can help if you give the best put,
