VVT-i, i-VTEC, CVTC Engine Care

Perhaps you have heard the car with VVT-i or i-VTEC or CVTC especially for new cars over the 2000s, the third term is in fact the same can be said that the technology of fuel efficiency through optimization of engine performance, engine optimization is done by setting the time opening the valve on the engine, the valve opening timing of this utilizing the oil pressure in the engine.

Flexibility of valve opening time this makes the engine power more evenly so that the acceleration of the car better than a car engine without VVT-i technology owned by Toyota or Honda's i-VTEC and CVTC of Nissan, at a constant speed (acceleration 0) This technology can save fuel so some circles say this technology can save fuel (not wrong too), precisely this technology is the technology to optimize the power generated by the engine with the valve opening timing using signals from the engine oil pressure.

VVT-i, i-VTEC, and CVTC Engine Care

Care VVT-i engine technology, i-VTEC and CVTC is worth noting, especially for fans of this saving tech car so as not to lose the expected engine performance with economical fuel consumption. There are at least three components that must be considered in the treatment of this new engine car, among other things: lube, air filter and tire size.

Grease or oil

New car engine has different characteristics with the old car engines both in terms of material, technology, level of precision, so that the lubricant used is also different from the old cars 90s output, the new cars what else is using the technology of the valve opening timing this requires an appropriate level of viscosity oil which new car requires more dilute the oil with the recommended engine oil code. The new Nissan cars more use code viscosity engine oil with SAE 10W-30 while suzuki use SAE 10W-40 oil, the suitability of this oil is very closely related to the 3rd and associated with the specification / oil pump's ability to obtain optimum engine lubrication, besides valve opening timing system VVT-i and i-VITEC CVTC because this technology to measure the oil pressure in the engine as a benchmark.

The use of oil that does not fit the standard car will weigh working oil pump so that the machine can not work optimally and the calculation of the valve opening time becomes inaccurate and fuel efficiency was not achieved, the owner of the car with the technology required to use the requested oil according to standard machines.
In addition to the standard oil car owners must also consider changing the oil on time, the oil will lose its viscosity due to its use in addition to the old oil is not replaced in a dirty state will cause the crust in the machine and cause blockages in the lubrication system. Disruption of the lubrication system also affects the accuracy of the automatic valve system settings open this.

Air Filters

The air filter must be clean (must be cleaned every few months), it is necessary to keep the engine from dirt entering through the filter which is not able to filter out the dirt again, if the filter is dirty possibility of dust will enter the combustion chamber and cause the crust that inhibits performance machine, dust is also possible going into the lubrication system through the cylinder wall lubrication systems such detrimental above cases clogging the engine lubricant which results in the performance of the valve opening timing can not function as they should be.

Tire size

Valve opening control system also considers the speed of a car in a set time opening and closing of valves in addition look at the engine oil pressure, a simple computer system knows the speed of the car to look at the speedometer on a car, use a different tire than the original tires for example larger or smaller will affect speedometer accuracy, use of improper tire will affect the performance of the valve opening time so that the performance of this technology will be reduced, possibly the owner of the car with this technology after the replacement tire felt to be reduced engine performance.
