“…The utilization of the lambda sensor for monitoring oxygen levels in the exhaust gasses plays a pivotal role in facilitating the catalyst's effective oxidation of CO and HC. Additionally, this monitoring contributes to the decomposition of NO x , enhancing overall catalytic efficiency [27]. Since catalytic converters began to be used, the reduction of gases emitted by vehicles has been noted, and with recent advances in their durability and efficiency, they are relied upon to reduce pollution [28].…”

This study focuses on the detailed analysis of exhaust emissions from multi-point fuel injection (MPFI) engines by manipulating the injection parameters through a programmable electronic control unit. In addition, tests are carried out using different generations of catalytic converters and checking that their working temperature is correct using a thermographic camera, verifying operation, to evaluate their effect on emission reduction. Detailed comparisons of the results between these configurations will allow the identification of the combination that reduces emissions the most without compromising engine efficiency and performance. This research aims to promote a more sustainable approach in the automotive sector by properly configuring systems, but also by demonstrating the technical robustness of their application in vehicles. It has also helped to verify that varying injection and ignition parameters help to fine-tune fuel injection, resulting in efficient combustion. Combining this variation with catalytic converters has further reduced exhaust pollutants.

“…One of the applied aspects in this area of research is the RICE exhaust system. New data on the gas dynamics and heat transfer of unstable processes in the exhaust system can be useful for refining valve strength calculation methods [16], improving the environmental performance of the engine [17], reducing exhaust noise [18], creating systems for the conversion of the thermal energy of exhaust gases [19,20] and updating the design of exhaust systems [21,22].…”

It is a relevant objective in thermal physics and in building reciprocating internal combustion engines (RICE) to obtain new information about the thermal-mechanical characteristics of both stationary and pulsating gas flows in a complex gas-dynamic system. The article discusses the physical features of the gas dynamics and heat transfer of flows along the length of a gas-dynamic system typical for RICE exhaust systems. Both an experimental set-up and experimental techniques are described. An indirect method for determining the local heat transfer coefficient of gas flows in pipelines with a constant temperature hot-wire anemometer is proposed. The regularities of changes in the instantaneous values of the flow rate and the local heat transfer coefficient in time for stationary and pulsating gas flows in different elements of the gas-dynamic system are obtained. The regularities of the change in the turbulence number of stationary and pulsating gas flows along the length of RICE gas-dynamic systems are established (it is shown that the turbulence number for a pulsating gas flow is 1.3-2.1 times higher than for a stationary flow). The regularities of changes in the heat transfer coefficient along the length of the engine?s gas-dynamic system for stationary and pulsating gas flows were identified (it was established that the heat transfer coefficient for a stationary flow is 1.05-1.4 times higher than for a pulsating flow). Empirical equations are obtained to determine the turbulence number and heat transfer coefficient along the length of the gas-dynamic system.

“…This study considers the impact of modernization of injection ignition control and steering precision on vehicle driving dynamics [5]. This system changes the drop in pressure and temperature of the flue gas and, therefore, asks for a different composition of catalyst [6]. In addition to using an appropriate ignition system configuration, combustion characteristics similar to diesel fuel autoignition can be achieved for high gasoline replacement rates [7].…”

In the automotive field, the development of motorcycle ignition systems has been able to improve engine performance more fuel efficient. TCI has the advantage of transferring high voltage to the spark plug, the results issued from TCI are greater than the CDI system. To find out the results of motorcycle performance, namely the TCI ignition system and spark plugs on performance and exhaust emissions from motorcycles that use fuels such as Premium Ron 80, Pertalite Ron 90, and Pertamax Ron 92. Fuels that have octane that matches the bicycle motorcycles, in addition to the better performance of motorcycle engines, the fuel consumption is also more economical. In this study there are three variables, namely variations in rpm, performance and exhaust emissions. The results of the study of motorcycles that use the Ron 92 Pertamax fuel have far more torque and power than those that use the Ron 80 premium fuel and the pertalite Ron 90, while the HC levels produced by Ron 80 and 90 fuels tend to increase more than Ron fuel 92 which is between 65 - 228 ppm. CO2 levels were 12.53% while Pertamax was 10.74%, and pertalite was 11.17%, while the CO content produced was small at 3750 rpm resulting CO levels of 0.08 ppm. It can be concluded that the ignition produced is more stable which uses Pertamax fuel compared to using premium and pertalite fuel.
