Downsized Engine
Suzuki to introduce 660cc, 63.5 mpg engine in minicar lineup
For the first time in almost 16 years, Suzuki has developed a brand-new engine for its minicar lineup. This 660cc mill is equipped with stop/start technology and is expected to deliver a fuel efficiency rating of nearly 63.5 miles per gallon (U.S.), – a boost of approximately 20 percent versus the automaker's current three-cylinder, 660cc engine. The addition of this high-tech engine would position Suzuki's minicars to achieve a fuel econ
Aggressive engine downsizing held back by low-speed preignition problems?
Engine downsizing is considered an effective method to reduce emissions and improve fuel efficiency. The basic concept is simple: replace a larger engine with something that displaces less and, typically, packs a turbocharger to make up for any lost power. One impediment to engine downsizing is low-speed preignition (LSPI). Preignition occurs when the combustion chambers ignites prior to the spark event. This causes advanced combustion timing which can lead to heavy engine knock and catastrophic
