About This Product
Students trace the fuel-air mixture entering the cylinder, its compression, the spark-ignition power stroke and the exit of burnt gases through the exhaust valve, then explain why the cycle needs two crankshaft revolutions. In the THEORY OF MACHINE LAB it also supports teaching of valve timing and serves for viva preparation and technical display.
Frequently Asked Questions
Q1. How does it differ from a four-stroke diesel engine trainer?
It demonstrates spark ignition of a fuel-air mixture, whereas a diesel trainer demonstrates compression ignition with fuel injection. Both cover the intake, compression, power and exhaust strokes.
Q2. Which strokes does the trainer show?
Intake, compression, power and exhaust, completing one cycle over two crankshaft revolutions.
