2011 Chevrolet Cruze -- 40 + mpg highway and finally getting out ahead of the competition with GM's homegrown hard work and good design.
Ecotec 1.4L turbo Airflow -- Almost 140 HP worth of performance from just 1.4L displacement thanks to turbo-charging.
Outside air is drawn into the intake air box by the turbocharger compressor wheel. The compressor wheel is being driven by hot Exhaust gases coming out of the Exhaust manifold. The air is forced through an Intercooler by the compressor wheel and then travels to the intake manifold. The intake manifold distributes the air to the cylinders where fuel is added and the combustion process takes place. A wastegate opens to regulate the compressor drive power by letting excess Exhaust gases escape through the Exhaust pipe.
The turbocharger's on-demand performance in the 2011 Chevrolet Cruze is like having two engines in the same vehicle -- one for fuel economy and one for power.
Proper sizing of the turbocharger allows the small 1.4L engine to sip fuel under lighter driving conditions because the extra turbo power, normally associated with a larger sized engine, is held in reserve.
New Mercedes Benz V8 biturbo engine
http://www.eurocarnews.com - Mercedes Benz AG - In the new V8, Mercedes-Benz engineers achieved a high output from a lower displacement primarily by using one turbocharger for each bank of cylinders. The intake air is forced into the eight combustion chambers at an overpressure of up to 0.9 bar, with the turbine blades rotating at up to 190,000 rpm. The turbochargers and their hot gas ducting are accommodated on the outsides of the cylinder heads. This enables the Intercooler module with its air/water Intercooler and charge-air distributor to be located inside the V of the engine -- a solution which Mercedes-Benz engineers found to be advantageous following a long series of tests. This is confirmed by the output and fuel consumption figures achieved in practice.
The Mercedes-Benz engine designers configured the turbochargers to provide high torque even at low engine speeds. Compared to the previous engine, the result is an increase in torque at 2000 rpm by more than 45 percent. An outstanding 700 Nm is available between 1600 and 4750 rpm. The driver therefore perceives no turbo lag, but experiences the same pleasant and effortless performance from the new V8 as that delivered by a mighty, naturally aspirated 7-litre engine.
The engine is based on a diecast aluminium crankcase with aluminium/silicon cylinder liners. The developers adopted the basic and connecting rod journal diameters from the preceding engine, while raising the piston compression height for load reasons by just about 4 millimetres. By reducing the lift and shortening the connecting rod by two millimetres, it was possible to retain the interior height of the crankcase. Showing the high efficiency of the turbocharged V8, which is configured for premium petrol (RON 95), the compression ratio of 10.5:1 remains unchanged versus the naturally aspirated preceding engine.
New Nissan Juke 1.6 Liter Turbo Engine - ANIMATION - Very Cool Video
Watch a video on the new 1.6 liter 4 cylinder turbocharged engine in the new Nissan Juke. The video is animated and systematically show the engine in pieces and then puts it together and shows how it runs. The 1.6 turbo is part of the wave of new small displacement turbocharged gas engines coming to this country. The reason is to provide high fuel economy, low emissions and high power output when needed.
Forced Induction - Supercharger vs. Turbo Charger
This video was made to describe in moderate detail the differences between Superchargers and turbo Chargers, as well as describing the components, advantages, and disadvantages to each. Complementing the speaking track is a slideshow of related pictures and videos. I hope this video helps some of you curious up and coming mechanics to better understand methods of forced induction. Please comment maturely, and enjoy!

Volkswagen TSI Engine 3D Animation
https://www.eurocarnews.com - Volkswagen AG - The most effective means for reducing fuel consumption is so-called downsizing. By reducing displacement and thereby lowering frictional losses, a lower specific fuel consumption can be achieved, and this goes hand in hand with better efficiency. The innovative path to the future is the combination of Supercharger and turbocharger. The Supercharger compensates for typical drive-off weakness at low revs of purely turbocharged gasoline engines, while the turbocharger really puts out at higher revs. This combination of two types of chargers is unique among engines mass-produced worldwide.

Audi turbochargers with variable turbine geometry
In all TDI engines from Audi, the turbochargers have variable turbine geometry on the Exhaust side. Variable turbine geometry (VTG) technology builds up torque smoothly and without delay, even at low engine speeds.

General Motors Engineer gives us the lowdown on Ecotec 2.4
Chris Meagher, Chief Engineer for this engine, was kind enough to spend a few minutes with me to discuss the 2.4 Ecotec. For those who don't know, GMs Ecotec 2.4L I-4 has been awarded Wards Auto World magazines 2010 10 Best Engines for North America. The direct injected engine with variable valve timing helps deliver segment-best highway fuel economy in GMs new crossovers, the Chevrolet Equinox and GMC Terrain. The engine also debuts in the all-new Buick LaCrosse and Regal sedans this year.
2011 Chevrolet Cruze Test Drive Impressions
I recently visited the East Coast for a GM sponsored introduction to the 2011 Chevrolet Cruze. In addition to driving the turbo 1.4L Cruze, I was also able to drive the Toyota Corolla S and Honda Civic for comparison. As always, I was very rushed and I apologize for the sloppiness that is my video style. Hopefully you are able to get something from this. A written review will be forthcoming. General Motors covered my expenses to attend this media preview.
