Abstract
The engine performance affected by the it’s running life or say total working hours of its utilization. As the engine gets used over the time, the performance of the engine also reduces due to two main factors i.e. mechanical losses and wear and tear. This study was conducted with the hypothesis that even the engine is properly maintained considerable losses are occurred in engine performance as the usage increases. Two engines having power 5 HP and 10 HP were selected for the study. The heat balance method was used and different performance characteristics parameter were analyzed. The maximum rated power of 5 HP engine was found 3.72 kW and the maximum rated power of 10 HP engine equal to 7.4 kW. The main reason of this lower performance are due to poor governing, thermal and mechanical losses. This study helps to analyze and predict the performance of the engine over the years. The maximum rated power of 5 HP engine and 10 HP engine was found to be 3.1 kW and 5.8 kW against the declared value of 3.72 kW and 7.4 kW respectively which may be due to poor governing, thermal and mechanical losses.
