This multi-technology system allows the complete study of a combustion engine with injection and electronic ignition. This heat engine is coupled with a DC electric motor to drive (start, adjust) or brake (dynamic load). An electronic injection card has been developed to conduct injection and ignition studies through a PC interface.
The test bench for a 4-stroke thermal engine consists of a block consisting of an internal combustion 4-stroke combustion engine and an onboard card for controlling the advance angle and the injection time.
An electric motor / generator is initially used as a starter, in order to start the engine. It then flows into an active load, to modulate the load applied to the engine.
It is a complete instrumented system allowing to control the ignition parameters (angle of advance and intensity of the spark), of the injection (duration and moment of the injection), and the resistant torque applied to the engine .
The injection and ignition control parameters are transmitted in real time by microcomputer thanks to a user-friendly and intuitive interface. Consumption measurements can be made. The heat engine and the electric motor are fixed on a base plate and connected by a belt. The set is hooded for soundproofing and security. The exhaust gases are evacuated by suction.
