More turbochargers, direct injection coming to China as plug-in interest drops

China seems to be hedging its bets on meeting stiffening emissions and fuel economy regulations, and addressing consumer demand for cleaner air. Electric vehicles remain part of the strategy, but their high cost, limited range and lack of infrastructure have kept sales at a slow pace. Hmm, that kind of sounds familiar, doesn't it?

Toyota planning 2.0T, more CVTs among other powertrain developments

Aside from its hybrid technology, Toyota has fallen behind the competition in terms of vehicle powertrains which could leave popular cars like the Toyota Camry and Toyota RAV4 lagging behind the competition. While most of its rivals have started using gasoline direct injection, turbochargers and some have moved to Continuously Variable Transmissions (CVT) to balance performance and fuel economy, many Toyota models are still using underpowered engines and outdated transmission technology.

Toyota getting help from Gazoo Racing to bring downsized turbo engines to market

According to a report by TheDetroitBureau.com, Toyota is teaming up with Gazoo Razing (full name: Gazoo Racing Masters of Nürburgring) to kickstart development and retail rollout of small-displacement, turbocharged engines. While Toyota is the undisputed leader in hybrid sales, the 274,927 gas-electric vehicles sold in 2011 – that's in total, not just the Prius – still represent a tiny portion of overall sales. By contrast, the EcoBoost-equipped Ford F-150 alone sold 100,000 uni

Report: Toyota plans to add turbo, direct-injection to most of lineup

Toyota has big plans for its model lineup, as the automaker intends to introduce 11 new or redesigned vehicles by 2012. This will be accomplished by offering hybrid versions of existing models, as well as introducing all-new hybrid vehicles. However, Toyota's focus isn't going to be entirely on improving the electric half of the hybrid equation. The automaker is looking at ways to produce more efficient gasoline engines, and turbochargers and direct fuel injection are both in the cards.

Volvo expands engine lineup with two fuel-efficient, 1.6-liter 4-cylinder GTDI mills

Come this fall, Volvo's range of engines will be bolstered with the addition of two new mills that feature a wide variety of the currently available mileage-enhancing tricks and power-boosting techniques. The engines, dubbed the T3 and T4, border on tiny with each mill displacing just 1.6 liters. Nonetheless, they boast power numbers that range from 150 horsepower (in T3 trim) to 180 hp for the T4 unit. Both the T3 and T4 make due with just four-cylinders, but the addition of a turbocharger and

AutoblogGreen Q&A with Transonic Combustion: Can supercritical fluids give a 30% mpg boost?

Given that the traditional four-stroke Otto-cycle engine piston engine only has a thermal efficiency of 25-30 percent, there is clearly still plenty of room for improvement. While most of the green automobile attention in recent years has been focused on electrification, liquid fuels still have about 100 times the energy density of today's best lithium-ion batteries, a difference that probably won't change significantly any time in the near future.

Nissan introduces 1.2L supercharged-DI three-cylinder for Micra (March)

With the introduction of the new Nissan Micra/March minicar comes an all-new engine for the brand. The HR12DE is the first of many similar engines from various automakers expected to debut in the next several years. This is a 1.2-liter inline-three with direct injection and a supercharger.

Delphi to discuss next-generation direct injection at SIA Congress

At the SIA (French Automotive Engineers Society) Congress in Rouen, France this week, Delphi will be presenting information on its latest-generation direct fuel injection and control systems for diesel engines. Delphi produces both electromagnetic servo injectors and the more advanced piezo-electric injectors. For the latest editions of both systems, Delphi has bumped the maximum operating pressures from the 2,000 BAR level that has been used in the last few years up to 2,400 BAR (34,800 psi). T

Report: GM struggling to market fuel efficient turbo technology

In the automotive realm, marketing can sometimes prove just as important as the actual product. Take, for instance, Ford's well-regarded EcoBoost technology, which couples turbocharging with direct injection to produce more horsepower and reduce fuel consumption. Would it surprise you to hear that General Motors has had similar technology on the market for over three years?
