Honda Ape Type D 50cc with 5-speed Gear!

Honda Ape Type D 50cc

While I was browsing at Honda worldwide website to look for Honda CB Twister as featured in Paul Tan’s blog, I encountered this interesting bike named Ape.
It is a very interesting bike since it is a 4-stroke 50cc engine with 5-speed transmission, front and rear disc brake, full aluminum cast wheels and PGM-FI fuel delivery system!

2010 Honda CB Twister 110cc

2010 Honda CB Twister 110cc

Honda has launched CB Twister 110cc to be marketed next year on January February 2010 in India.
Honda CB Twister target the young with stylish design adopted from large European super-bikes. This combination creates a low maintainance, high fuel efficiency and cutting-edge looks.
Low maintainance is achieved by using a low displacement cylinder with naked design that makes engine access is easy.
High fuel efficient is contributed by the application of low-friction 4-stroke cylinder and also by the low displacement inherent of the bike.

Honda CV-Matic: 2010 Cub-style Scooter Automatic Transmission

Honda CV-Matic Transmission Cut-Out

Honda CV-Matic Air Flow

If Yamaha has come with YCAT, Honda also has developed its own next generation compact automatic transmission named CV-Matic.
Compact automatic transmission will get use to final drive using chain and sprocket like normal moped. This mean that you have modify your AT bike to be torquey (more pickup) or speedy just by changing the ratio of the front and rear sprocket.
The airflow of the CV-Matic is important to keep the heat away from the drive belt for good normal operating temperature.
There are many name for this kind of transmission using belt drive namely Ultra V-Matic by Honda, Super CVT by Suzuki or Xtronic by Nissan (for car usage) which actually refer to the same basic concept of Continuous Variable Transmission (CVT) using belt driven shaft fitted with cone shaped wheel. There’s a great article for you to read at HowStuffWorks about CVT here: http://www.howstuffworks.com/cvt.htm
Honda CV-Matic will only be available on 2010, but Yamaha YCAT already teased in Yamaha Motor Vietnam in Yamaha LEXAM.

I know some of you who ride Honda scooters might have problem looking for the the JASO MB motor oils. JASO MB is required for the scooters as scooters use dry clutch system compared to normal 4-stroke bike that use wet clutch system. Wet clutch system is a system where the transmission, clutch and gears share the same lubricant oil with the piston, cams and crankshaft.
Dry clutch is the one that is not shared. That’s why you have transmission oil for scooters.
JASO MB oil have friction modifiers compared to JASO MA which does not have the friction modifiers.
Even though that is the case, you still can use any motor oil with API SG and above grade, but make sure there is not ‘Energy Conserving’ label on the pack.
I have checked my Honda iCon manual book for the transmission oil and it is only required for 0.10L.
For more info, try to search Wikipedia entry with the word ‘JASO MB’.

CDI + Circuit Breaker / Rev-limiter / Cut-off Switch

CDI is known to give spark to the running engine, whether it is 2-stroke or 4-stroke. Inside a standard CDI circuit, there is a circuit breaker or rev-limiter or cut-off switch which limit the revolution of the engine. How does it work? Read on the article taken from Wikipedia. This article is about electrical circuit breaker but it can be used to relate to rev-limiter or cut-off switch in engines. In fact, we can’t get away from electrical system when we are discussing about engines.

A device to open or close an electric power circuit either during normal power system operation or during abnormal conditions. A circuit breaker serves in the course of normal system operation to energize or deenergize loads. During abnormal conditions, when excessive current develops, a circuit breaker opens to protect equipment and surroundings from possible damage due to excess current. These abnormal currents are usually the result of short circuits created by lightning, accidents, deterioration of equipment, or sustained overloads.

Formerly, all circuit breakers were electromechanical devices. In these breakers a mechanism operates one or more pairs of contacts to make or break the circuit. The mechanism is powered either electromagnetically, pneumatically, or hydraulically. The contacts are located in a part termed the interrupter. When the contacts are parted, opening the metallic conductive circuit, an electric arc is created between the contacts. This arc is a high-temperature ionized gas with an electrical conductivity comparable to graphite. Thus the current continues to flow through the arc. The function of the interrupter is to extinguish the arc, completing circuit-breaking action.

In oil circuit breakers, the arc is drawn in oil. The intense heat of the arc decomposes the oil, generating high pressure that produces a fluid flow through the arc to carry energy away. At transmission voltages below 345 kV, oil breakers used to be popular. They are increasingly losing ground to gas-blast circuit breakers such as air-blast breakers and SF6 circuit breakers.

In air-blast circuit breakers, air is compressed to high pressures. When the contacts part, a blast valve is opened to discharge the high-pressure air to ambient, thus creating a very-high-velocity flow near the arc to dissipate the energy. In SF6 circuit breakers, the same principle is employed, with SF6 as the medium instead of air. In the “puffer” SF6 breaker, the motion of the contacts compresses the gas and forces it to flow through an orifice into the neighborhood of the arc. Both types of SF6 breakers have been developed for ehv (extra high voltage) transmission systems.

Two other types of circuit breakers have been developed. The vacuum breaker, another electromechanical device, uses the rapid dielectric recovery and high dielectric strength of vacuum. A pair of contacts is hermetically sealed in a vacuum envelope. Actuating motion is transmitted through bellows to the movable contact. When the contacts are parted, an arc is produced and supported by metallic vapor boiled from the electrodes. Vapor particles expand into the vacuum and condense on solid surfaces. At a natural current zero the vapor particles disappear, and the arc is extinguished. Vacuum breakers of up to 242 kV have been built.

The other type of breaker uses a thyristor, a semiconductor device which in the off state prevents current from flowing but which can be turned on with a small electric current through a third electrode, the gate. At the natural current zero, conduction ceases, as it does in arc interrupters. This type of breaker does not require a mechanism. Semiconductor breakers have been built to carry continuous currents up to 10,000 A.
