- •
Study to optimize piston squish area for LPG lean burn engine was carried out.
- •
30% squish area piston results in improved performance at all operating conditions.
- •
Piston squish area beyond 30% causes instability in combustion towards lean limit.
- •
Lower HC emissions were obtained with 25% and 30% squish area pistons.
- •
NO emission increased with 25% and 30% compared to 35% and 40% squish area pistons.
