Honda is one of the most popular vehicles in North America a record it has held on to firmly. The vehicle was introduced in 1972 housing a latitudinal engine with an 1169cc capacity engine.

The Honda Civic engine has always been a fuel efficient and with the introduction of the VTEC engine, this has only been maximized. The Honda Civic engine has always been reliable and with the entry of the new technology, the engines are more effective.

VTEC stands for variable timing and lift electronic control. This means that the engines fuel consumption is changing constantly with regards to the speed at which the vehicle is moving. The higher the vehicle speed, the higher the lift and vice versa. This aspect of the Honda Civic engine has allowed the vehicle manufacturer to remain on the cutting edge of technology in this day of fuel efficiency and cost cutting.

This Honda Civic engine system was developed by Honda in order to improve engine capacity and cut down on the overall fuel consumption. More charge could be taken into and ...
... out of the respective cylinders all of which was hinged on the amount of power the engine was using at the time.

The VTEC system endows the vehicle with multiple camshaft profiles with the Honda civic engine using two cam lobes therefore improving the engines overall capacity. The shift from the rotary to the linear sort of engine movement has proved more successful in making the engine more economical by reducing the amount of fuel being burnt up.
There are several sub categories within the VTEC engine systems and these include the Advanced VTEC cam engine. This Honda Civic engine has a variable phase control which means that the engines power out put is increased or decreased depending on the load. For automobiles that do not have this capacity, the engine continues to consume the same amount of power whether the vehicle is moving at 50 or 120 Mph. This results in fuel wastage making the vehicle costly to run and maintain. The variable lift and timing control associated with the advanced VTEC Honda Civic engine system is excellent for those interested in a vehicle that allows them to control both power and energy consumption.

The i-VTEC system uses direct fuel injection to keep the vehicle running. This further improves on the engines proficiency by reducing the amount of fuel being burnt up to produce energy. This particular system is associated with a unique form of valve control and is part of Honda's new and innovative system that is out to make vehicles as environmentally friendly as possible. This is effortlessly attained because the less power the vehicle uses, the less fuel it needs for its daily operations and the less pollution it causes in the long run.

The i-VTEC VCM comes into play in certain Honda civic engines when fewer valves are operational as a result of the vehicle traveling at lower speeds. Once the vehicles speed dips to around 80km/h, three of the cylinders are deactivated making the Honda Civic engine more capable.

The SOHC i-VTEC engine has this mechanism activated as long as the vehicle is producing less than 3500 RPM. If on the other hand the vehicle is producing more than this, then extra valves are activated by the system in order for the vehicle to perform as it should.

There are several variations of the VTEC Honda civic engine but they are all designed to be as efficient as possible. From torque optimization all the way to fuel efficiency, this technology from Honda is excellent for the 21st century and beyond.
