New Revolution of Diesel Engines Technology

Diesel engine technology for more intense performance and no less than engines using gasoline. In addition to more fuel efficient, new generation diesel engine is also lighter and although small capacity but the energy released is larger than the previous generation.

The hard work of Honda's engineers in Japan and Europe that produce new innovations such as an i-DTEC 1.6 liters diesel engine for the latest European Civic series car that will be market early next year.

The diesel engine was claimed to be a new revolution in the diesel engines technology. Because the machines are manufactured at Honda's factory in Swindon, England that has brought Honda's Earth Dream Technology, that is claimed to produce 120 PS of power, torque of 300 Nm at 2,000 rpm, and the emissions levels of carbon dioxide (CO2) only 94 g/km.

Not only that, the development of this engine also utilizes lightweight material such as aluminum for the cylinder head and cylinder block. The result, this diesel engine was the lightest in its class or 47 kg (104 lb) lighter than the Honda's 2.2 liters i-DTEC engine.

In making innovative breakthroughs, each engine components have precision redesigned including manufacturing techniques. The thickness of the cylinder is thin enough that only 8 mm compared with the previous 9 mm on 2.2 liters of capacity machine. The piston and its handlebars are also made lighter.

To improve the performance of the machine is done by minimizing mechanical friction so that the same as a gasoline engine. "The components are working machines are made to be able to rotate optimally to reduce friction," said Tetsuya Miyake, project leader of the 1.6 liters i-DTEC engine.

To increase efficiency, Honda added Garrett's 4th generation turbocharger. This new turbo devices, where its nozzle variable were more precision. In addition, with a precision turbo rotation that was controlled by the engine's computer.

As a result, the engine works ranging from low, moderate to high rotation. On the fuel injector, use Bosch's solenoid type that works on 1,800 bar of pressure. With high pressure, the fuel spray faster and produce small particles atomization. A more complete combustion to produce great power and the resulting exhaust gas of this engine become more environmentally friendly. *** [HONDA | MOTOR TREND | EKA | FROM VARIOUS SOURCES | OVI | PIKIRAN RAKYAT 30112012]
