Abstract

The development of applied diesel engine is required in process of understanding its characteristic. The characteristic can be analized from performance parameter of diesel combustion engine by carrying out an experimenal works (performance test). The used engine which is used is Four Cylinder 21. Type of Toyota Diesel Combustion Engine which is commonly known as LF80 or Kijang Krista. The experiment is carried out by modifying some parts of the engine, mainly at flywheel to measure rotation and give load. Testing method that is used in this experiment is giving a constant load at variated rotation. Some parameters which are measured in performance test are as follows: Rotation (n). Temperature of Inlet Air (T). Temperature of Exhaust-Air (T2). Inlet Cooling Water (Ty), Outler Cooling Water (Ta). Period of Fuel Consumption (t). Volume of Fuel, and Volume of Cooling Water Testing is ranging from rotation 800 rpm to 2800 rpm with increment of 200 rpm. This machine is constant as loaded at 50 psi. The rotation is controlled by adjusting the accelerator gas pedal. The data which are obtained and calculated are used as an experimental data. Thus as the performance parameter of diesel combustion engine. Those data which are obtained are Brake Power. (bp), Mean Effective Pressure (MEP), Volumetric Efficiency (n.). Thermal Efficiency (M), Fuel-Air Ratio (F/A), and Specific Fuel Consumption (sfc). The highest Brake Power (bp) is obtained at the rotation of 2800 rpm which is 44.61 kW and the lowest one at the rotation 800 rpm which is 12.75 kW. The Mean Effective Pressure (MEP) are remain constant at any level of rotation speed is 123.05 kPa. While Volumetric Efficiency (1) has the highest efficiency at the rotation of 1600 rpm which is 63,972% and the lowest one at the rotation of 1000 rpm which is 32.348%. The highest Thermal Efficiency (ta) is at the rotation of 1000 rpm which is 67.24% while the lowest at the rotation 800 rpm is 53.104% Fuel-Air Ratio (F/A), higher ratio at rotation 1200 rpm is 0.199, lower at rotation 1600 rpm is 0.1102. The highest Specific Fuel Consumption (sfe) is at the rotation of 1800 rpm which is 0.063 kg/kWh and the lower at the rotation of 1000 rpm which is 0.05 kg/kWh.
