| What is a 4-stroke diesel engine?As the

| reciprocating

| | temperature high enough for ignition.The
|
| actions of pistons. One stroke means one
| |
| | fuel is supposed to burn so fast as to
|
| linear motion of the
| |
| | explode. So there is
|
| piston in one direction. When the piston

| | no point in injecting it more than it

| moves in the opposite

| | can burn. If the fuel is
|
| direction, that is counted as another

| | not able to catch fire, it will remain
|
| stroke.For a 4-stroke engine, the piston
| |
| | in the piston as unburnt
|
| has to move up, then down,
| |
| | fuel.So the timing of the fuel injection

| then up again, and then down again to

|
| complete one cycle of the

| combustion cycle. As you might have

| | exhaust stroke. In this stroke, all the

| engine, we need a fuel, a

| | exhaust valve(s) will have opened to

| heat source, and oxygen coming together
