This means that the traditional all-mechanical powertrain will be complemented with more and more electric components. This range from mild hybrid to full hybrids, plug-in hybrids and eventually a fully electric powertrain. Most future projections estimate that most LDV will have a combustion engine and thus this should be optimized for fuel efficiency and ultra-low emissions. This session focus on the benefits electrification can give for engine design with smaller operating range required by the engine and what can be achieved for both gasoline and diesel technology. It includes reports from the SIP project in Japan that reached 50% brake thermal efficiency for both engine types.

It is a common understanding that carbon-free in automobiles is a keyword to survive in the future. Therefore, electric vehicles will become mainstream in the future, and it is said that ""the internal combustion engine has no future."" In order for the internal combustion engine to survive toward 2050, the key is whether carbon-free can be achieved. Shuji Kimura, NISSAN MOTOR COLTD 8:45 a.m. ORAL ONLY Challenge for Super Lean Burn Combustion Technology for SI Engine to Achieve 50% Thermal Efficiency The Cabinet Office in Japan organized a grave project as Innovative Combustion Technology in the Cross-ministerial Strategic Innovation Promotion Program (SIP) for 5 years from fiscal year 2014 to fiscal year 2018. The presentation introduces Research and Development on the Super Lean Burn Concept for Gasoline Engines by the Gasoline Combustion Team with 28 universities. To achieve 50% thermal efficiency of gasoline SI engines, the lean burn operation is one of valid techniques to increase thermal efficiency by reducing heat losses with low temperature combustion. Super lean mixture of more than 2.0 excess air ratio is applied a single cylinder SIP prototype engine in order to reduce the combustion temperature less than 2,000K and to decrease heat losses as well as NOx emission. However, the prolongation of combustion duration due to decrease in laminar flame velocity, and the increase in cycle-to-cycle combustion fluctuation and/or quenching become barriers to realize the super lean-burn engine. So, the prototype engine is designed to generate a high intensity tumbling flow of 25m/s, and combustion acceleration effects by turbulence generated by tumble collapse are employed. The engine has a spark ignition system suppling 10 times longer discharge duration and higher electric discharge energy than that of conventional engine to realize the stable cycle-to-cycle ignition and combustion.

SwRI continues to examine the potential for improving the ICE and, given the challenges of the future, investigates the potential that an even closer symbiosis between the ICE and the electric motor has to decrease CO2 emissions while keeping the personal automobile an affordable solution for the masses. By examining the potential for improving ICE efficiency by using an electric motor to reduce constraints on the engine, we show that combining the motor and engine in a true hybrid system has enormous potential for reducing CO2 emissions. Terrence Alger, Southwest Research Institute Monday, April 12 Session 2 – Heavy-Duty Session Code HEE2 Room TBD Session 10:00 a.m. Heavy-duty engines are rapidly evolving to meet changing customer requirements as well as new greenhouse gas and pollutant emissions regulations. To meet these needs, manufacturers are undertaking significant efforts to rethink many aspects of the engine and its surrounding systems. This session focuses on emerging heavy-duty engine trends and technologies that are intended to increase capability, fuel efficiency and/or reduce emissions. Topics for this session include the reduction of parasitic and combustion heat losses, in-cylinder combustion phenomena, emissions formation, advanced air-path control, aftertreatment devices, waste-heat recovery systems, and integration into electrified powertrains.

It becomes much more important to reduce greenhouse gas emissions from the prime mover of automotive vehicles. However, it is not sufficient to achieve the future anticipating target only with the reduction of mechanical loss by the internal combustion engines’ (ICEs) design optimizations, because of their limited contribution to the thermal efficiency. Heat loss reduction is certainly the most essential measure to increase in energy resource which is transformed into the growth in indicated thermal efficiency (ITE). Nevertheless, exhaust heat loss should not be reduced further to maintain the current efficiency of both turbocharger and exhaust aftertreatment system, which are indispensable for not only the modern diesel engines but the diluted gasoline engines. Therefore, the reduction of cooling loss from the in-cylinder wall is currently attracting attention. Thermal barrier coating (TBC) technique has been expected as one of the measures to reduce cooling loss in the cylinder since 1980s. However, the insulating effects of TBC for ICEs have been still very limited even if the thermal conductivity of the TBC materials is very low. This presentation reviews the published papers on TBCs and discusses about the future direction of the investigation into complicated heat loss mechanism from the cylinder. Noboru Uchida, New Ace Inst. Co., Ltd. 10:30 a.m. ORAL ONLY Experimental Evaluation of Novel Thermal Barrier Coatings in a LD Diesel Engine The subject of this presentation is improvement of the thermal properties of plasma sprayed thermal barrier coatings (TBC) for internal combustion engines. Four measures for improvement were evaluated: i) modification of the coating's microstructure by using a novel suspension plasma spraying method, ii) application of gadolinium-zirconate, a novel ceramic material with low thermal conductivity, iii) polishing of the coating to achieve low surface roughness, and iv) sealing of the porous coating surface with a polysilazane. Six coating variants with different combinations of the selected measures were applied on the piston crown and evaluated in a single cylinder light duty diesel engine. Results will be shown for indicated efficiency, heat losses and exhaust losses, as well as engine out emissions. The new TBC microstructure from suspension plasma spraying in combination with the use of gadolinium-zirconate showed promising results with respect to indicated efficiency and heat loss reduction. The presence of the evaluated TBCs also has a noteworthy adverse effect on the apparent rate of heat release, for which different explanations will be discussed.
