More than 5 million general-purpose engines were manufactured by Honda in 2009. Approximately 70% of the general-purpose engines manufactured by Honda are supplied as OEM engines to other manufacturers of power products. Current range (US & Europe) 1-cylinder. GX series Horizontal shaft GX100 (OHC) (2002–) (98cc) GX120 (OHV) (1991–) (118cc)
It is fuel injected, has an aluminum-alloy cylinder block and cylinder head, is a SOHC 16-valve design (four valves per cylinder) and utilizes Honda's i-VTEC system. The R series engine has a compression ratio of 10.5:1, features a "drive by wire" throttle system which is computer controlled to reduce pumping losses and create a smooth torque ...
The valve timing of a diesel engine also depends on tappet clearance of the inlet and exhaust valves. If tappet clearance is less, then valve will open early and close late. [2] If tappet clearance is more, then valve will open late and close early. Tappet clearance is measured by an instrument called feeler gauge.
In the 1980s, many U.S. production engine remanufacturers began reaming valve guides, rather than replacing them, as part of their remanufacturing process. They found that by reaming all the valve guides in a head to one standard size (typically 0.008 in. diametrically oversized), and installing remanufactured engine valves having stems that are also oversized, a typical engine head can be ...
The Honda Revolution Control valve is designed and works in principle like the "AETC system." A small computer monitors engine RPM and adjusts a two-blade exhaust valve with an electric servo. Honda equipped many two-stroke motorcycles such as the NSR125 and NSR250 models with RC - Valve power plants.
A hydraulic tappet, also known as a hydraulic valve lifter or hydraulic lash adjuster, is a device for maintaining zero valve clearance in an internal combustion engine. Conventional solid valve lifters require regular adjusting to maintain a small clearance between the valve and its rocker or cam follower .
Honda's first production V6 was the C series; it was produced in displacements from 2.0 to 3.5 liters.The C engine was produced in various forms for over 20 years (1985–2005), having first been used in the KA series Legend model, and its British sister car the Rover 800-series (and Sterling).
The J-series engine was designed in the United States by Honda engineers. It is built at Honda's Anna, Ohio, and Lincoln, Alabama, engine plants. The J-series is a 60° V6 unlike Honda's existing 90° C-series engines. Also unlike the C series, the J-series was specifically and only designed for transverse mounting.
