The customer complains of loss of performance and turbocharger noise. The turbocharger oil supply may be restricted, causing oil starvation and resulting in the seizing of the turbocharger assembly.
Turbochargers are great for adding power to any gas or diesel-powered engine, but are especially useful in small displacement engines. The boost to airflow that a turbocharger provides increases the breathing efficiency of the engine for more horsepower and torque.
Buick started playing with turbochargers in 1976 when it paced the Indianapolis 500 with a Century equipped with a special turbocharged 3.8L V6. The actual pace car needed the boost cranked up to 22 psi to keep pace with the field. It produced 300 hp while the commemorative edition only had a V8 with 165
Utilizing electronically controlled wastegates and bypass valves With the ability to increase fuel economy by up to 20% on gas vehicles and up to 40% on diesel vehicles, manufacturers have resorted to turbochargers to compensate for lowered engine displacement. Additionally, the improvements on turbocharging technology have increased the number of turbocharged vehicles on American roads.
Extreme temperatures cause the oil circulating through the turbocharger oil feed line to burn. The coked oil buildup restricts oil flow, which leads to turbocharger failure. The oil line may appear fine externally.
Honeywell Turbo Technologies is using its experiences in racing to fine-tune the performance and durability of its turbochargers. The company pushes its motorsport turbo applications to the absolute limit on roads and racetracks around the world, with the aim of improving its products.
The power that a naturally aspirated engine can make is limited by its displacement and how efficiently you can make it breathe with cylinder head, camshaft and induction system modifications. The engine can only inhale so much air because the atmospheric force that’s pushing air into the engine is only 14.7 lbs. per square inch at sea level. To make matters worse, atmospheric pressure decreases with elevation. Air density also decreases with temperature because hot air is thinner than cold air.
When you hear the name Cummins, what is the first thing that comes to mind? Most of the time, if you have any knowledge of trucks, a Dodge truck is the first thing that comes to mind. The Cummins diesel engine has always had a great reputation for reliable diesel power. Though the Cummins diesel engine can be found in many applications, it seems to obtain most of its credit from drivers of over the road trucks.
Back in the 1990s, GM wasn’t making too many waves in the diesel truck market. The 6.2L and 6.5L engines had been around for sometime, but they were no match for the release of the Cummins 6BT in the Dodge truck in 1989 and the Ford Powerstroke in 1994.
With the ability to increase fuel economy by up to 20% on gas vehicles and up to 40% on diesel vehicles, manufacturers have resorted to turbochargers to compensate for lowered engine displacement. Additionally, the improvements on turbocharging technology have increased the number of turbocharged vehicles on American roads. Some turbocharger manufacturers have even projected the number of turbocharged vehicles in the U.S. to quadruple in the next five years.
In recent years, the primary driving force behind engine innovation has been the never-ending quest for better fuel economy with little or no sacrifice in performance. Government regulations and rising fuel prices are forcing automakers to develop new technologies and powertrains that squeeze more power out of every drop of fuel while producing less pollution and greenhouse gas (carbon dioxide) emissions.
As gas prices remain high this summer driving season, Honeywell Turbo Technologies says it is working with auto manufacturers to meet the increase in demand for affordable and fuel-efficient downsized turbocharged engines.
