Product name

　　Honda Accord engine

　　Feature

　　The main structure of this training bench is made of the actual Honda Accord engine, which can perfectly realize the functions of the original car engine system. The composition of the electronic control system of the DOHC i-VTEC engine is shown in Figure 7. Program-controlled fuel injection PGM-FI system monitors various input sensor signals at any time, such as throttle valve position, intake air temperature, coolant temperature, intake pressure, exhaust air-fuel ratio, crankshaft/camshaft position, etc., after reprogrammed (reprogrammed) ) of the PGM-FI determines the optimal fuel injection amount and ignition timing, so that the power, fuel consumption and emissions have reached a higher standard. 4 standard.

　　The intelligent DBW (Drive-by-Wire Throttle System) system replaces the traditional throttle control with electronic signals. In addition to receiving the accelerator pedal demand signal and making the engine respond in time, the system also responds to the engine. Optimized for driving conditions, by monitoring accelerator pedal position, throttle opening position, vehicle speed, engine speed and engine vacuum, this information ultimately determines throttle control sensitivity, allowing the engine to have both good power response and compatibility with other systems. good coordination.
