Innovative Use of Basic Technologies for a High-Efficiency, Low-Cost Small Displacement Gasoline Engine

<div class="section abstract"><div class="htmlview paragraph">India, with its low per capita income vast population and growing middle class, represents a significant market for low-cost, fuel-efficient automobiles. As the largest two-wheeler market globally, a transition to four-wheelers is underway, further driving the demand for affordable vehicles. This necessitates the design and development of low-priced vehicles equipped with efficient and economical powertrains.</div><div class="htmlview paragraph">Globally, stringent regulations like Corporate Average Fuel Economy (CAFE), Worldwide Harmonized Light Vehicles Test Cycles (WLTC), and Real Driving Emissions (RDE) are pushing manufacturers to develop fuel-efficient vehicles. India has also adopted similar regulations, including CAFE2 and Bharat Stage 6-Phase 2 (BS6-2), to improve fuel economy and reduce emissions. These regulations, coupled with the growing demand for affordable vehicles, have spurred innovation in engine technology.</div><div class="htmlview paragraph">In response to these challenges, Maruti Suzuki India Limited (MSIL) has consistently focused on enhancing the efficiency of its small gasoline engine (0.8L) for entry-level hatchbacks. This has been achieved through a series of technological advancements implemented across multiple generations of the engine. <span class="xref">Figure 1</span> flashes the overview of generation wise technologies upgradation and Gen-3 is the latest one with the highest efficiency in its segment.</div></div>
