Abstract

The increasing need for fuel and the increasingly soaring prices have resulted in many automotive manufacturers creating vehicles that consume more fuel efficiently with ideal engine performance. Torque and power are measures that describe the performance output of an internal combustion motor. These two parameters describe two different performance elements, depending on the use of the vehicle. The selection factor for the type of valve mechanism is based on its technological capability in activating engine power, increasing engine efficiency, reducing exhaust emissions, effectiveness and efficiency in reducing fuel consumption. Focusing on reducing fuel consumption, the most important thing is how there is a good system for engine control, on the engine itself, assistive devices and a good overall transmission system, so one of the valve mechanisms that promises to improve fuel efficiency is effective. Also improvements to exhaust emissions are the CVTC (Continuously Variable Timing Control) valve mechanism. The purpose of this study was to determine the effectiveness of the CVTC valve mechanism on engine power. CVTC has the ability to effectively control the intake camshaft to provide the most optimal valve timing for engine conditions, improve torque at all speed levels, and save fuel.

Abstract

To determine the characteristics and capabilities of the machine, a series of tests were carried out using the SOHC system. In this test, several parameters can be shown, namely; torque, effective shaft power, average pressure, specific fuel consumption.The research was carried out at engine shaft rotation of 1200 rpm to 4000 rpm with 6000 rpm as a benchmark for loading on gasoline engine performance measurements were made on fuel consumption, load, rotation and flow rate of each with a measuring instrument, while the testing equipment used was a gasoline motor. Daihatsu Taruna 1500 cc. Torque as a function of rotation of the Daihatsu Taruna Type CSX engine has a higher torque. The engine output power as a function of the shaft rotation The Daihatsu Taruna Type CSX engine has a larger shaft power. The engine provides driving performance at high rpm and is also fuel efficient. Effective engine power as a shaft rotation The Daihatsu Taruna Type CSX engine has an effective engine power. The average effective pressure between the Daihatsu Taruna Type CSX engine and the EFI (Electronic Fuel Injection) fuel supply system. These results indicate that the Daihatsu Taruna engine is more powerful at high engine speed with maximum torque and remains efficient in fuel consumption.
