Variable Valve Timing Theory and Principles
There’s no doubt that engine specialists will begin seeing more variable valve timing (VVT) designed engines in their shops, as the generation of vehicles equipped with this technology begins to make its way into the service industry. In fact, the current versions of VVT were popularly introduced into domestic production about 10 years ago. Operating
Timing Belt Tips on Accord 2.2L and 2.3L Engines
These tips outline the belt replacement for the popular 2.2- and 2.3-liter Accord engines. The other Honda engines are similar, but don’t require the balance belt. They shouldn’t present any challenge to the experienced tech, but there are some things to keep in mind as you tackle these jobs. The 3.0-liter V6 models use a hydraulic
Just in Time – Addressing Timing Component Replacement and Upgrades
The timing components that drive a camshaft affect valve timing, ignition timing (if the engine has a cam-driven distributor), compression, engine performance and fuel economy. Because of this, the timing components must be in good condition with minimal wear and slop, and they must be durable enough to maintain accurate timing for the service life
BorgWarner Launches its New Low-Friction Timing Chain
BorgWarner’s next-generation 6.35 mm inverted tooth silent engine timing chains are launching on engines from Mitsubishi, Suzuki, Hyundai, General Motors Korea and one Chinese automaker. The innovative engine timing chain is designed to reduce friction, resulting in as much as 0.3 to 0.6 percent improvement in fuel economy based on customer testing. BorgWarner will produce
The Inner Workings of Variable Valve Timing
Variable Valve Timing (VVT) is a way to advance/retard valve timing, and change duration, overlap and even lift in some applications while the engine is running. VVT is computer-controlled and typically uses oil pressure to change the position of a phaser mechanism on the end of the camshaft to advance or retard cam timing. VVT
Replacing Timing Belts on VW and Audi 4.2L 8-cylinder Engines
Many timing belts have different change intervals even in the same car line. The change intervals can be different not only because of engine size, but also due to model year. The following are helpful tips for timing belt replacement on the VW and Audi 4.2L 8-cylinder engines. Many timing belts have different change intervals
ContiTech Says Timing Belts Drive Modern European Engine Designs
Timing belts on the advance: European automakers are increasingly turning to timing belts again instead of chains to drive timing gear. Timing belts on the advance: European automakers are increasingly turning to timing belts again instead of chains to drive timing gear. “In terms of improving fuel efficiency and cutting CO2 emissions from internal combustion
Rebuilding Liberty: Timing Belt Service on Jeep Liberty Engines
The 2.4 L I4 PowerTech is a Neon engine variant based on the Chrysler engine that was designed originally for the Dodge and Plymouth Neon compact car. The naturally aspirated 2.4L 4-cylinder PowerTech engine provided 150 hp (110 kW) and 165 lb.-ft. (224 Nm). In 2002, the Jeep Liberty was the first Jeep to use the two
Front Timing Cover Oil Leak Reported on Toyota 1GR-FE Engine
Oil leaks have been reported on some 2003-2007 Toyota 4Runners and FJ Cruisers with the 1GR-FE engine. Some 2003 – 2007 model year 4Runner, FJ Cruiser vehicles with 1GR-FE engines may display evidence of a small oil leak located where the Bank 1 cylinder head, engine block, and timing cover meet. Use the following repair
Oil Leak From Front Timing Cover Reported on Some 2005-2006 Toyota 2GR-FE Engines
Use the repair procedure below to diagnose and correct this condition. Repair Procedure 1. Inspect the location where the Bank 1 cylinder head, engine block, and timing cover meet for signs of an oil leak. 2. Use an oil dye to confirm the source of the oil leak. 3. Remove and reseal the timing cover
Phaser-Style Variable Valve Timing System Controls and Operation
By Matt Dixon, assistant professor, Southern Illinois University Vehicles with variable valve timing (VVT) have become commonplace over the last decade. Even more commonplace are engines that use a phaser to manipulate camshaft position and, hence, valve timing. (See Figure 1.) The phaser style of VVT is the focus of this article. Figure 2: The
Gaining Performance from Ignition Timing
The cool thing about ignition timing is you can usually get a considerable performance increase for little or no money. But, some time and effort will be required. Let’s start with a simple explanation of why we need spark advance and how much of it we want. First – When you hook up the timing
Tight Engine Timing Belts Can Cause Havoc
If one day it sounded like a cat was being tortured under the hood, yougot out your trusty wrenches, loosened the generator mounting bolts,and tore up your knuckles as you used a pry bar, pipe or 2×4 to pryaway until it stoped making noise. You then tightened the bolts againand went on your merry way.
Variable Valve Timing Systems
By the early 1990s, almost all import automotive manufacturers had a successful variable valve timing (VVT) system in production. These systems offered higher performance from smaller displacement engines at higher rpm. As these vehicles exceeded their new car warranties, technicians learned the ins and outs of these systems and how regular oil changes could increase
Variable Valve Timing Can Help Save V8s, Environment
Not that I don’t supportthe environment and being responsible in our efforts to save the planet– I do. But the passion for the thunder of a throbbing,pavement-pounding V8 is, well, similar to that of the how your heartskips a beat when you think of your first love. What if you could stillhave the power, have
Revised Timing Belt and Tensioner Setup Procedure for 1998-2000 Ford 2.0L Engines
During a timing belt servicing, refer to the following service procedure for details. Note: To achieve proper timing belt tension, the camshaft sprocketbolts should be loosened enough to permit the sprockets to turn freelyon the camshafts. With cam sprocket bolts loosened and cylinder #1 attop dead center (TDC), crankshaft must be rotated to TDC in
Modification of Timing Belt Tensioner Bracket on 2004-2005 Subaru Engines
Affected applications: 2004MY Forester; 2005MY Legacy and Impreza On SOHC engines, the shape of the bracket and the size of the 2 (upper side) installation bolts were changed. On DOHC engines, the shape of the bracket was changed and ribs added to increase rigidity. PRODUCTION LINE CHANGE The new style tensioner brackets were used in
