Abstract

The study on water injection system for naturally aspirated engine was conducted in order to evaluate the emission and performance of test vehicle. This project includes the development of water injection system for vehicles and testing the performance. The vehicle performance in term of emission, torque and horsepower is observed. The performance before and after installation of water methanol system was compared. Based on the analysis, it shows that the performances of the engine in term of torque and horsepower is improving compared to standard vehicle. Emission value also shows a reduction on harmful gasses that contribute to the air pollution. The data for emission was measured using exhaust gas analyser. The emission performance complies with EURO 6B standard. Significant reduction in Hydrocarbon (HC) emission and improvement of air fuel ratio (AFR) closer to the stoichiometric ratio. Reduction on HC is good for our environment shows perfect combustion due to the water methanol system. These projects can be further improved in future for better engine performance
