Why Diesel Engines Make More Torque Than Gasoline Engines

The host of YouTube channel Engineering Explained, Jason Fenske starts off his video, ‘5 Reasons Diesel Engines Make More Torque Than Gasoline’, asking his viewers if they had noticed that diesel engines have higher torque ratios than their gasoline counterparts. But why is that?

This very educational video explains the reasons in five easy to understand segments. While there isn’t enough space here to go into the detail of the video the five main reasons fall under these headings: Compression ratio, speed of combustion, bore versus stroke length, use of turbocharging and the energy density of diesel.

For each segment, Fenske explains with useful imagery and technical diagrams. If you aren’t a car nut, torque is basically force multiplied by distance - and it is what causes your car to accelerate. For car enthusiast beginners this blog post gives a great introduction to torque, how to measure it and what it can do in your car.

Fenske has a passion for cars which he has used to unpack the engineering of how they work. He brings his knowledge and passion to his 1 million subscribers with a down to earth presenting style.

He backs up his friendly persona with solid data, good animations, and clear whiteboard diagrams to answer all your car related engineering questions. The video topics range from ‘Do you need winter tires?’ to the more complex 'Turbo lag versus boost threshold'.

So whether you are a hardcore speed freak or just curious about what’s happening under the hood, Engineering Explained is a great knowledge source.
