AIR AND EXHAUST SYSTEMS AND TURBOCHARGERS

1. GENERAL

1. GENERAL

The power of any Diesel engine is determined by the amount of fuel burnt in each cylinder per cycle and the speed at which it can run.

1. GENERAL

The power of any Diesel engine is determined by the amount of fuel burnt in each cylinder per cycle and the speed at which it can run.

The quantity of air provided by turbocharging is so great that the amount of fuel burnt per cylinder is not limited on this account but because of the temperature that can be withstood by exhaust valves, cylinder heads and pistons.

The quantity of air provided by turbocharging is so great that the amount of fuel burnt per cylinder is not limited on this account but because of the temperature that can be withstood by exhaust valves, cylinder heads and pistons.

Diesel fuel requires about 14.5 times its own mass of air for its complete combustion.

2. TURBOCHARGE FUNCTIONS

a) Pressure charging

b) Scavenging

The more oxygen during the engine compression stroke, the larger the amount of fuel to be ignited and therefore an increased engine output developed.
