ENGINE ECONOMICS

THE AUTHOR CONSIDERS THE ENERGY PROBLEM IN RELATION TO THE PRIVATE CAR, WITH PARTICULAR REFERENCE TO EXHAUST GAS POLLUTION. OWING TO THE LARGE INCREASES IN THE COST OF CRUDE OIL SOURCES OF POWER, OTHER THAN THE PETROL ENGINE, NEED TO BE INVESTIGATED. DIESEL ENGINES HAVE A THERMAL EFFICIENCY OF 28-33%, COMPARED WITH 24-26% AND 10-16% FOR THE PETROL ENGINE AND BATTERY ELECTRIC VEHICLES RESPECTIVELY, BUT THEY ARE EXPENSIVE AND NOISY. THE ADVANTAGES AND DISADVANTAGES OF ELECTRIC CARS ARE DISCUSSED. THE OVER-EMPHASIS OF EXHAUST GAS POLLUTION, WHICH IS NOT A PROBLEM WITH ELECTRIC CARS, IS CONSIDERED. THE POLLUTION PROBLEM CAN BE SOLVED BY THE MODERN APPROACH TO COMBUSTION CHAMBER AND INDUCTION SYSTEM DESIGN. A FILTER DEVICE, WHICH WILL REMOVE 70% OF THE LEAD INPUT TO AN ENGINE, IS BEING DEVELOPED. THE USE OF GAS TURBINES AND WANKEL ENGINES IS MENTIONED. IT IS PREDICTED THAT THE KAROL ENGINE WILL OVERTAKE THE WANKEL ENGINE AND BECOME THE ROTARY ENGINE OF THE FUTURE.
