MAY 22, 2012
While gasoline costs were the number one reason cited for wanting a more fuel-efficient vehicle (at 90%), more than half of respondents also had other reasons, including a desire to be more environmentally friendly (62%) and concern about the nation’s dependence on foreign oil (56%).

The Manufacturers of Emission Controls Association (MECA) released a report assessing market-ready technologies being commercialized by suppliers of emission control and efficiency components for heavy-duty diesel vehicles to meet lower intermediate standards for oxides of nitrogen (NO x ) by 2024 as a transition to final standards in 2027.

Highly turbocharged alcohol-fueled direct-injection spark-ignition (DISI) engines operated at a high compression ratio could be as or more efficient than diesel engines while also providing advantages of lower vehicle cost, lower emissions and higher power, according to a recent modeling study by Leslie Bromberg and Daniel Cohn at MIT.

The new MY2014 Mercedes-Benz Sprinter van for the US now features a 2.1L, 4-cylinder diesel with a t-speed automatic transmission as standard. The familiar V6 diesel is available as an option. liter four-cylinder diesel engine produces 161 hp (120 kW) and 265 lb-ft (359 N·m) of torque at 1,400-2,400 rpm. Click to enlarge.

A heavy-duty exhaust valve guide with thermal deformation and temperature color scaling demonstrates high side load at high temperatures in contact with the exhaust gas. The solid lubricant package, combined with vacuum oil impregnation, delays valve stem scuffing in high temperature, heavily side-loaded applications. Click to enlarge.

CO 2 and NO x certification test data for heavy-duty diesel engines certified from 2002 through 2019. It is important to state that there are several technology paths to achieve these levels of emissions, and some of them can simultaneously lower greenhouse gas emissions, such that the NO x reductions do not compete with the CO 2 reductions.

However, while Mazda plans to offer hybrid vehicles in the medium-term, its engineers are pushing hard to increase the efficiencies of both the gasoline and diesel platforms, moving toward what they call “the ideal Internal Combustion Engine.” Extreme compression ratio rather than downsizing. Although downsizing—i.e.,
