Engine Efficiency of Cars – Sankey Diagrams The U.S. Department of Energy (DOE) is funding research projects that target the increase of efficiency of car engine. The Sankey diagram shown in this post on the Green Car Congress blog visualizes that only 25% (green arrow) of the energy from combustion is used as “effective power” for mobility and accessories, while 40% of the energy is lost in exhaust gas. Where the Energy Goes: Gasoline Vehicles Fuel Economy Where the Energy Goes: Gasoline Vehicles. Only about 12%–30% of the energy from the fuel you put in a conventional vehicle is used to move it down the road, depending on the drive cycle.The rest of the energy is lost to engine and driveline inefficiencies or used to power accessories. Internal combustion engine Diagram describing the ideal combustion cycle by Carnot. An internal combustion engine (ICE) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit.

How Electric Cars Work | HowStuffWorks A gasoline engine, with its fuel lines, exhaust pipes, coolant hoses and intake manifold, tends to look like a plumbing project. An electric car is definitely a wiring project. In o­rder to get a feeling for how electric cars work in general, let's start by looking at a typical electric car to see how it comes together. How do car engines work? Explain that Stuff Car engines are much more efficient: they waste less energy and put more of it to work. What's so clever about them is that they burn fuel in closed containers, capturing most of the heat energy the fuel releases, and turning it into mechanical energy that can drive the car along.
