What Year Did Gm Start Vvt

In 1993, GM and other car companies were working on a new technology called Variable Valve Timing or VVT. VVT is a system that allows the engine to change the timing of the valves based on driving conditions. This means that the engine can run more efficiently and with less emissions.

GM was the first company to put this new technology into production cars, starting in 1996.

GM has used Variable Valve Timing (VVT) on its production engines since the late 1980s. The first GM engine to use VVT was the 4.3L V6 that was introduced in 1988. VVT allows the engine to “breathe” better, which improves performance and fuel economy.

GM’s Ecotec 2.0L turbocharged four-cylinder engine, which is used in a variety of vehicles including the Chevrolet Cruze and Buick Regal, uses VVT on both the intake and exhaust valves.

6.2 Afm Years

Assuming you would like a blog post discussing the 6.2L AFM engine: The GM 6.2 liter V8 Ecotec3 L86 is an engine produced by General Motors for use in full-size heavy duty pick-up trucks and SUVs. The L86 is part of GM’s small block engine family and shares many features with other engines in that family such as the 5.3L and 6.0L engines.

It was introduced in 2014 for the 2015 model year Chevrolet Silverado HD and GMC Sierra HD. The engine is also used in the Chevrolet Tahoe, Suburban, and Silverado 1500, as well as the GMC Yukon, Yukon XL, and Sierra 1500. The L86 uses Active Fuel Management (AFM) which allows it to operate on four cylinders when under light loads to save fuel.

When more power is needed, all eight cylinders are activated automatically. The transition between four-cylinder mode and eight-cylinder mode is seamless and imperceptible to the driver. The L86 has several features that contribute to its durability including forged connecting rods, hardened valve seats, cast aluminum cylinder heads with integrated exhaust manifolds, chain driven dual overhead camshafts (DOHC), and roller followers with hydraulic lash adjusters – no adjustment required over the life of the engine!

All of these features work together to provide an engine that can handle heavy workloads day after day without breaking a sweat. If you’re looking for a durable and powerful engine for your next full-size truck or SUV, consider the GM 6.2 liter V8 Ecotec3 L86 – you won’t be disappointed!

When Did Gm Start Vvt?

GM’s VVT (Variable Valve Timing) technology first appeared on the 1997 LT1 V8 engine. It was a revolutionary new way to improve engine performance, and it quickly became one of GM’s most popular technologies. Today, VVT is found on nearly all of GM’s engines, and it has helped make GM one of the leaders in engine performance.

What Year Did the 5.3 Get Vvt?

The 5.3L VVT engine was introduced in 2007 for the GMC Sierra and the Chevrolet Silverado. This engine is still used in many GM vehicles today. The VVT system helps to improve fuel economy and performance by varying the timing of the intake valves.

How Do I Know If My 5.3 Has a Vvt?

The 5.3 L VVT (Variable Valve Timing) is a feature on the engine that allows for increased performance and fuel efficiency. To determine if your 5.3 has this feature, look for the following: 1. A “VVT” or “Variable Valve Timing” badge on the engine itself.

This is usually located on the valve cover. 2. If you have an OBD-II reader, check for codes P0010 and P0011. These indicate that VVT is active and functioning properly.

3. Check your owner’s manual or maintenance schedule.

Does Chevy Have Vvt?

Chevy does have VVT, but it’s a fairly new technology so not all models are equipped with it. VVT, or Variable Valve Timing, is a system that allows the engine to adjust the timing of the valves based on operating conditions. This can result in better fuel economy and performance.

Car Tech 101: Variable valve timing explained


In 1997, GM was the first automaker to offer VVT on the LT1 small-block engine in the Corvette. VVT allows the engine to “breathe” by opening and closing intake and exhaust valves at different times during the four-stroke cycle. This results in more power, better fuel economy and reduced emissions.
