- The paper presents selected results of tests on the Fiat Panda I car powered by 1.2 dm3 spark ignition engine. The engine had production installed fuel system with the single-point petrol injection. To improve its in-service performance, the engine was fitted with the multi-point injection fuel system. The assessment of the indicators of the work of the engine, fitted with single-point, or alternatively, multi-point injection fuel system, was conducted on the basis of the tests performed on the MAHA chassis dynamometer. First, tests were run for single-point injection fuel system. Next, the same tests were performed when the engine was fitted with the multi-point injection fuel system. In the tests, engine power, torque, fuel consumption and the concentrations of the exhaust gas components were measured. The latter included carbon monoxide CO, carbon dioxide C02, hydrocarbons HC, nitrogen oxides NOx, and oxygen 02. AVL Digas 4000 exhaust gas analyser was used to take measurements of the concentrations of the basic components of the exhaust gas and of the excess air ratio %u03BB. The investigations were conducted by performing the inertia test and by using the dynamometer to determine the basic indicators of the engine operation. In the investigations, the crankshaft rotational speed ranged from 1500 to 6500 rpm with 500 rpm step. The experimental results made it possible to evaluate how the manner and site of fuel delivery affect the engine -work indicators.
