The message that gasoline-fueled engines are yet to die will be given by Nissan Motor Co at the Los Angeles auto show next week. This despite the fact that the Japanese car maker was an early mover in the electric vehicle market.
The development of the internal combustion technology will be continuously done to enhance the usefulness of the engines over decades, said Shinichi Kiga, head of Nissan’s gasoline engine project group.
And one the new technologies that Kiga plans put to use will be showcased ion the engine of a new Infiniti QX50 sport utility vehicle to be brought before the public eye in Los Angeles.
The technology of a variable compression ratio system would be used for the first time in the QX50. While the current gasoline combustion engines being used in the industry have an average maximum thermal efficiency of 20 to 30 percent, the new technology based engines would push up the numbers to around 40 percent which is almost twice the current levels. The amount of power that an engine is able to derive from a unit of fuel is termed as thermal efficiency.
While the policy makers are keen on ending the dominance of the internal combustion engine in global transportation, the Nissan/Infiniti VC Turbo will definitely present a challenge to them. Experts are of the view that despite the fact that the costs of batteries for electric cars is getting reduced, any enhancement in the efficiency of internal combustion engines would certainly impact the time when electric vehicles would be able to attain cost parity independent of government subsidies in the future.
James Chao, Asia-Pacific chief of consultancy IHS Markit Automotive, said that firther development of the efficiency of the internal combustion engine technology is “one of the most overlooked trends in the industry”. “These advances beg the question. Are EVs the best solution to the issue of vehicle greenhouse emissions?”
At present, the key trade-off between power and efficiency of a gasoline-powered engine is the choice of an optimal compression ratio for combustion and the new engine, which has been christened as VC-Turbo for use in marketing, makes use of new electronics and software for achieving the optimal compression ratio.
Producing equal power and torque, the 3.5-liter V6 engine is replaced by the smaller 2-liter, four-cylinder VC-Turbo engine averages which delivers about 30 to 35 percent better fuel economy. torque is the power that an engine is able to generate for acceleration and the new engine is able to generate the same amount of torque as a diesel engine, Nissan says. This achievement has been unable to be achieved by the conventional gasoline engine so far.
Engines that are able to achieve a thermal efficiency of 50 percent is the ultimate aim of Kiga and wants to make such engines fit for Infiniti and Nissan vehicles.
Some government regulators and a few industry officials or consultants have suggested that by 2030, the internal combustion engine would be dead and buried, there is wide ranging variety in the forecasts for the future of the internal combustion engines over the next 10 to 15 years. For example, prediction of a 14 percent overall market share for fully electric vehicles by the year 2030 is being predicted by the Boston Consulting Group,
