The engine is a fairly complex system, all parts work together to generate power converted into the motion of the car. The car engine also needs maintenance to keep the engine performance remains prime, it takes routine maintenance for components last longer and also do check if came a strange sound from the machine. The final project discuss about the analysis and checking throubleshooting machine daihatsu charade G10 and aims ti know the working of the 3 cylinder engine daihatsu charade G10, knowing the components of the machine daihatsu charade G10, and know how to measure the components of the machine daihatsu charade G10 in order to know the components still good ot not. After checking on component found components thats have worn out such as piston rings and cylindrical gaps that must be replaced on the component in order to restore engine performance back to normal conditioin. The result obtained after making fuel improvements more efficient about 21.47% in terms of power experienced an average compression increase of 22.05%.
