In the study, an exhaust gas purification system is applied to Diesel engine for automobile. In the system, a high pressure fuel injection and an electronic control are applied for improving a combustion process of the Diesel engine, increasing the thermal efficiency and reducing the particulate matters (PM). Furthermore, the residual PM is caught by use of a Diesel particulate filter (DPF). In addition, nitrogen oxides (NOx) are decreased by use of an exhaust gas recirculation (EGR) and a Selective Catalytic Reduction (SCR). The exhaust gas is purified completely by applying those combustion process improvement and after-treatment technologies. Before those technologies will be applied, the performance of a small Diesel engine for the test is examined with an introduced measurement system, and the present conditions of the engine are confirmed as a basis of comparison. In addition, a performance and characteristics of the measurement system are grasped under various operating conditions of the engine.
