Different Engine Honda CBR150R And Honda CB150R
Yesterday was dissected difference frame and legs CB150R and CBR150R (click here). Now turn the engine. Many thought CBR150R machine swallowed whole into CB150R, it's not.
There are altered, reduced and increased. Of course, that character is suitable for daily application, especially in urban areas with heavy traffic. To be clear, we ask directly on the PT Astra Honda Motor (AHM) as producer.
To be suitable for everyday use in the crowded streets, CB150R as an urban sport bike needs some adjustments. The one that made the machine was to change the duration of exposure camshaft or camshaft DOHC his type.
"Valve CBR150R entry remains the same as, but slightly modified dump valve. CB150R ex valve opens 35 degrees before BDC and closes 5 degrees before TDC. At CBR150R, ex valve opens 30 degrees before BDC and closes 0 degrees before TDC," said Edhi Sarwono , Technical Training Development of PT Astra Honda Motor (AHM).
This step was taken so that the peak power and torque feel more comfortable at a lower engine speed and make the engine to make it more cool. for relatively jammed streets. Another step taken in order to pull more responsive is the final gear change settings.
"If CBR150R wear front gear 15 and the rear 43 eyes in the back CB150R use larger gear is 15/45 eyes," said the friendly man who was familiarly called Edhi this. For the reduction of primary teeth fixed 75/23, also was the same as the ratio transimisi CBR150R that carries a 6 speed.
If it had been a two-step change, that are now added. In the machinery sector is diaplikasikannya kick starter that was not previously available on the CBR150R. No construction is modified. Because, the kick starter on the CBR150R as it already exists. So, just stay put.
Furthermore, adding Secondary Air Supply System (SASS) for helping to minimize exhaust emissions. Part is located in the cylinder head cover. When you see the reason why this component is added, it is the aftermath of the release of O2 sensor on the injection system that previously existed on the CBR150R but nil on CB150R.
SASS works by injecting oxygen into the discharge line, so that the poisonous CO gas will turn into CO2 and O2. This component is generally used motorcycle carburetor tech, was on the injection machine has been left out because they exhaust emissions cleaner engine relative injection. If so there is a reduction in technology then???
"With the application we were able to meet SASS Euro2 standards set by the government. So exhaust emissions also remain good," sure the man in the familiar cordial greetings Edhi. "In addition, other changes in the engine crankcase merely finishing outer cover right and left," added the man was friendly.
And finally, we can see performance data from website remsi PT AHM. Honda claims CB150R power is 17 PS at 10,000 rpm, while CBR150R reached 17.8 PS at 10,500 rpm. For torque, translucent CB150R Nm at 8,000 rpm 13.1, while CBR150R only 12.66 Nm at 8500 rpm.
