Abstract
The purpose of this study is to investigate experimentally the effect of water injection to intake manifold on the
engine performance and exhaust gas temperatures of a commercial engine. A four stroke, four-cylinder SI engine
was used for conducting this study. Water injections were used with five different water to fuel mass ratios: 0, 0.125,
0.2, 0.33 and 0.5 at constant load and variable engine speed ranging from 1000 to 4500 rpm.
The results indicate that the addition of water into the intake manifold reduces the compression work. The engine
torque, power and brake thermal efficiency increase as the water to fuel mass ratio increases. The average increase
in the brake thermal efficiency for 0.5 water to fuel mass ratio is approximately 2.4% over the use of pure LPG for
the engine speed range studied. It was also found that the proper brake specific fuel consumption and exhaust gas
temperature decrease as the ratio of water to fuel increases.
