COMPARISON BETWEEN DIESEL AND GASOLINE PASSENGER CARS.

In order to provide reliable information on the merit of Diesel compared to gasoline passenger cars in respect of performance, fuel consumption, exhaust emissions and noise, tests were carried out on a range of Diesel and gasoline powered vehicles. These tests were performed not only at constant speeds but also in simulated city driving conditions. The results of these tests have shown that, where direct comparisons are applicable, a Diesel engined vehicle has an advantage over the gasoline one in respect of fuel consumption and exhaust emissions but is inferior in respect of performance and noise.
