Diesel engines create more torque because they are a long blocks not short blocks since Torque=force times distance and power is force times distance times time if you have a longer distance but you use the same amount of force you will create more torque. the explosion in the combustion chamber is what creates the power not the torque and the more power pushing on the crank which is longer equals more torque but takes up power to create. That is the reason that powerful diesels use turbochargers to push more HOT air into the engine since there is no spark plug creating the explosion but it's the pressure creating heat that ignites it. And to create so much pressure the area inside the diesel has compression ratios of 16:1 to 21:1 instead of 8:1 to 11:1. And Diesel engines are Otto cycle engines all four strokes are.
