STEAM ENGINE

An external combustion engine using steam is described which has good efficiency at full power and even better efficiency at the low power settings common for passenger vehicles. The engine is compact with low weight per unit power. All of its components fit in the engine compartment of a front-wheel drive vehicle despite the space occupied by the transaxle. It readily fits in a rear-drive vehicle... Calculated net efficiencies, after accounting for all losses, range, depending on engine size, from 28-32% at full power increasing to 33-36% at normal operating part-load power settings. The part-load efficiencies are 50-100% higher than gasoline engines and about the same as diesel engines... A very modern vehicle engine that will help reduce oil imports, global warming and air pollution
