What kind of engine has two camshafts per cylinder?
A V or flat engine with a total of two camshafts (one per bank of cylinders) is a single overhead camshaft engine, not a double overhead camshaft engine. Regardless of number, the camshaft usually operates the valves indirectly via a rocker arm. Most SOHC engines have two valves per cylinder.
What makes a dual overhead camshaft a DOHC?
Generally, engines with dual overhead camshafts (DOHC) are higher performance engines, they produce more power, and can run at higher speeds. The camshafts have the job of opening the valves that let air into and exhaust out of the engine. The camshaft uses rotating lobes, called cams, that push against the valves to open them.
Where are the camshafts located in an overhead camshaft engine?
A dual overhead camshaft (DOHC) valvetrain layout is characterised by two camshafts located within the cylinder head, one operating the intake valves and the other one operating the exhaust valves.
Why was an overhead camshaft engine used in pushrod engines?
This expansion caused difficulties for pushrod engines, so an overhead camshaft engine using a shaft drive with sliding spline was the easiest way to allow for this expansion. These bevel shafts were usually in an external tube outside the block, and were known as “tower shafts”.
Are there two intake cam profiles per cylinder?
Instead, there are two different intake cam profiles per cylinder: a very mild cam lobe with little lift and a normal cam lobe with moderate lift.
How does the Honda VTEC engine timing system work?
A third option is to change the cam timing profile, of which Honda VTEC was the first successful commercial design for altering the profile in real-time. The VTEC system provides the engine with valve timing optimized for both low and high RPM operations.
What kind of timing does a Honda J engine use?
All J-series engines are gasoline-powered, use four valves per cylinder, and have a single timing belt that drives the overhead camshafts. VTEC variable valve timing is used on all applications.
How does VCM work on Honda J series engine?
The system uses VCM to turn off one bank of cylinders under light loads, turning the V6 into a straight-3. Some versions were able to turn off one bank of cylinders or one cylinder on opposing banks, allowing for three-cylinder use under light loads and four-cylinder use under medium loads.
