Engine Deposits

The article describes the threat posed by deposits harmful to the proper functioning of spark ignition engines. The areas of indirect and direct injection engines where the most dangerous deposits form are indicated. The factors having significant influence on the occurrence of this unfavourable phenomenon were collected and analyzed. Consequently, a simplified classification of factors influencing the formation of harmful deposits in direct and indirect injection spark ignition engines was made. In the research part of the project, a comparative study of the tendency of gasolines of different composition and physicochemical properties to form deposits was carried out. The criterion for evaluating the detergent properties of gasolines was the tendency to form deposits on intake valves in the case of indirect injection engine and on the injector in the case of direct injection engine. For this purpose, the previously widely used test procedure CEC F-05-93 relating to deposits formed on intake valves in SI indirect injection engines and the latest test procedure CEC F-113-KC relating to the most harmful deposits formed in injectors of DISI (Direct Injection Spark Ignition) engines were used. The purpose of the comparative study conducted was to determine if there was any relatively simple, identifiable relationship between the results of gasoline detergent property evaluations obtained at engine test sites differing in test engine generations, methods of conducting the evaluations, and type of engine deposits formed. As a result, no correlations were found between the testable engine sludge tendency results obtained from tests using the CEC F-05-93 and CEC F-113-KC procedures. Therefore, knowing the evaluation of gasoline conducted according to one of the above mentioned test procedures, one cannot conclude, predict or estimate the evaluation that will be obtained according to the other test procedure. Therefore, the results obtained according to one of the procedures do not allow extrapolation and evaluation of gasoline in terms of tendency to form harmful engine deposits according to the other procedure.

According to the title, the article compares passenger cars produced in versions with SIE engines (spark ignition engines) and CIE engines (compression ignition engines), taking into account the situation on the Polish automotive market. A group of 25 selected vehicle pairs equipped with the SIE and CIE engine versions has been presented. The measurable comparative criteria have been defined. The results of the comparison were presented in the form of graphs with a commentary. The situation on the Polish automotive market was also assessed in the context of a comparison of both types of vehicles. The final conclusions close the article.

The Impact

Among the alternative fuels existing for spark-ignition engines, ethanol is considered worldwide as an important renewable fuel when mixed with pure gasoline because of its favorable physicochemical properties. An in-depth and updated investigation on the issue of CO and HC engine out emissions related to use of ethanol/gasoline fuels in spark-ignition engines is therefore necessary. Starting from our experimental studies on engine out emissions of a last generation spark-ignition engine fueled with ethanol/gasoline fuels, the aim of this new investigation is to offer a complete literature review on the present state of ethanol combustion in last generation spark-ignition engines under real working conditions to clarify the possible change in CO and HC emissions. In the first section of this paper, a comparison between physicochemical properties of ethanol and gasoline is examined to assess the practicability of using ethanol as an alternative fuel for spark-ignition engines and to investigate the effect on engine out emissions and combustion efficiency. In the next section, this article focuses on the impact of ethanol/gasoline fuels on CO and HC formation. Many studies related to combustion characteristics and exhaust emissions in spark-ignition engines fueled with ethanol/gasoline fuels are thus discussed in detail. Most of these experimental investigations conclude that the addition of ethanol with gasoline fuel mixtures can really decrease the CO and HC exhaust emissions of last generation spark-ignition engines in several operating conditions.
