HONDA CIVIC 1

  -  

The norm for turbo engines used to lớn be "high power, low fuel economy." Honda" s VTEC TURBO is a new era engine that is both fuel efficient, & provides an enjoyable ride.

The 1.5L VTEC TURBO retains all the fuel economy benefits of a small engine, and by combining its turbo charger with a direct injection system and variable valve sầu timing mechanism, produces a feel of power that is smooth from low revs, exceeding the torque of a 2.4L engine, to the high end. Acceleration is exhilarating on any road, from urban driving lớn highways, và uphill climbs.In addition, the 1.5L VTEC TURBO is designed lớn perkhung well even on regular gasoline, so even more customers can enjoy its benefits.

Small displacement engines are fuel efficient and light, but compared lớn a large engine, vày not have sầu a much power or torque. Supercharging using a turbo charger overcomes the power problem.Honda" s VTEC TURBO realizes high fuel economy and exhilarating power through three vital technologies: Dual VTC for Intake and Exhaust, Direct Injection System & High Tumble Intake Port, & Highly-responsive Turbocharger with Electronic Wastegate.

The turbo engine" s disadvantage was that by sending high-pressure air inkhổng lồ the engine, its temperature and pressure would rise, resulting in knocking. The VTEC TURBO uses direct injection công nghệ lớn inject fuel directly into lớn the cylinders, lowering the temperature within the cylinders by the gasoline’ s vaporization heat. High tumble intake ports that strengthen intake airflow, và tumble flow maintaining pistons, allow fuel lớn be quickly & efficiently burned. By the cooling effect of direct injection & rapid combustion by high tumble flow, knocking is solved.

Conventional turbo engines could not supercharge efficiently at low revs, causing slow engine response. With the VTEC TURBO, Valve Timing Control (VTC) changes the timing for intake & exhaust valves khổng lồ operate, controlling the amount of time both types of valves are simultaneously open. This allows efficient supercharging even at low engine revs.

Conventional turbo engines suffered from "turbo lag." Acceleration lags behind depressing the accelerator, as exhaust energy has to lớn rise to spin the turbines, which then increase intake amount. With the VTEC TURBO, this problem is avoided by using a turbocharger with electronic wastegates equipped with small-diameter turbines that spin efficiently on small exhaust energy. The result is a sharp, responsive turbo engine, which rapidly responds lớn how the accelerator pedal is depressed.


The Intercooler is a device that reduces the temperature of intake air compressed và heated by the turbocharger, before it is sent khổng lồ the engine. Without the high-temperature air being cooled first, the temperature within the engine would rise, causing knocking. The intercooler also sends more air khổng lồ the engine by cooling intake air to reduce its density (as heated air expands and reduces air mật độ trùng lặp từ khóa & increases volume) allowing the engine lớn operate even more efficiently.


Turbochargers use high-temperature exhaust gas from the engine’ s combustion chamber lớn send air inkhổng lồ the engine. As turbocharged engines have high torque, the exhaust gas from the combustion chamber can exceed 1,000°C. Water jackets within the cylinder heads reduce exhaust gas temperature khổng lồ an optimal level, before it enters the turbocharger. Durability of the components, which means the turbocharger" s reliability, is increased.Water jackets also allow for cooling in addition lớn fuel cooling, helping to increase fuel efficiency.

Contrasting the 1.5L VTEC TURBO which is fuel efficient và fun, the 2.0L VTEC TURBO focuses on power. Inheriting the basic kiến thiết of the 1.5L version, the 2.0L VTEC TURBO is equipped with a variable lift mechanism và enhanced cooling performance, realizing higher output. The result is an engine with the fuel economy of a 2.0L straight 4-cylinder engine, & 320PS power, equivalent to a large 6-cylinder engine. The Civic Type R takes full advantage of the high performance & light weight of this engine, setting a new front-wheel drive sầu lap record*1of 7 minutes 43.80 seconds*2at the Nürburgring Nordschleife. The 2.0L VTEC TURBO engine is considerate of environmental performance demanded in these times, yet pursues an even more enjoyable driving experience.
