Variable Geometry Turbochargers
With the Green Revolution upon us, the turbocharger is making big waves helping boost efficiency and increase power in both performance vehicles and daily drivers. Turbocharged cars often experience “lag” at lower speeds due to the time required for sufficient exhaust pressure to build up and spool the turbo.
CRC Industries’ GDI IVD Intake Valve & Turbo Cleaner Debuts At 2016 AAPEX And SEMA Shows
The launch follows extremely successful test results on turbocharged engines, according to the company.
VIDEO: Turbochargers and Carbon Deposits
Andrew Markel explains the importance of taking extra steps to keep from damaging the turbocharger during a regular induction cleaning.
Water Instead Of Gasoline: Bosch Water Injection Innovation Can Reduce Fuel Consumption By Up To 13 Percent
Like many of the technologies introduced in recent years, the idea of water injection isn’t new. Water injection is emerging as a possibility today due to the convergence of fuel economy requirements, the increased accessibility of direct injection technology and the need for more enrichment due to the heating caused by downsizing with turbocharging.
Audi’s Five-Cylinder Engine Turns 40
Forty years ago, Audi presented the first five-cylinder gas engine in the second-generation Audi 100. Enhancements and new developments followed, with turbocharging, emissions control and four-valve technology, rally engines and five-cylinder diesel units. Today, the 2.5 TFSI in the Audi TT RS Coupé and Roadster carries on the great tradition of five-cylinder powerplants. The five-cylinder engines
AVI Adds ‘Diesel Day’ To Training Conference Lineup
The Group Training Academy, consisting of Pronto Auto Parts and Federated Auto Parts, is sponsoring diesel training at the 2016 AVI conference, which takes place alongside AAPEX.
BMW Tech Tip: Poor Performance, Noise From Turbocharger
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.
Installing Spark Plugs: Avoid Misfires
The potential for inadvertently creating a misfire is very real when installing new spark plugs. I say this because I’ve diagnosed many misfires created by greasy fingerprints, broken insulators and incorrect air gaps — all caused by poor installation procedures. But nothing is as simple as installing a spark plug, right? After all, a spark
High-Tech Tightening
When you build your engines, you put measured thought into every component you use. From the intake system to the exhaust manifold, everything has its place and nothing is installed without careful consideration. But what about the fasteners? Some of the most critical components are held together with relatively low-cost fasteners including screws, nuts and bolts, and studs. No matter whether you’re building a restoration showpiece, a high horsepower street machine or a stump-pulling torque monster, the fasteners you use are more critical than you may believe.
Turbo Trouble: How Turbochargers Work
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.
