The Technology behind the engine of motor scooters

Posted by Ainsley Aiken on July 18th, 2017

Have you ever seen the engine of a motor scooter? Engines of motor scooters are of the GY6 category which was originally developed by the multinational company branded as Honda. GY6 carburetors are understood to be strong and able engines which were later adopted by the manufacturers of scooter. Simultaneously, technical experts related to the engines of automobiles have admitted that these kinds of engines have been adopted by light vehicle manufacturers (ATV etc.). As a matter of fact, such kind of engines is adopted for various vehicles across Taiwan, PRC and South East Asia.

Design of a GY6 Engine for a motor scooter:

The design of a GY6 engine includes a single-cylinder, four-stroke engine. The engine is arranged in such a way so as to create a near horizontal orientation. The engine is cooled through passage of natural air. The entire structure remains to be displayed in a chain driven overhead camshaft. Fuel metering is done while the scooter runs in a constant velocity style.  

How do the engine ignite?

Ignition of the engine happens through pressing of a magnetic trigger. The trigger is located on the flywheel. Since the trigger is located on a flywheel, the ignition catches up with both the compression and exhaust strokes. This has been termed by the automobile engineers as "wasted spark" ignition". An integrated magneto provides 50 V AC power.  Approximately, about 20-30 V AC rectified and regulated to 12 V DC power is utilized in chassis accessories. This includes a lighting accessory and an accessory which includes a battery back up.

GY6 carburetors has been identified to be very strong engines which can ignite the following models

  • Vespa Grande,
  • Bravo  
  • Ciao model,
  • as well as Honda Camino/Hobbit scooters/mopeds.

Such engines are well equipped with an electric starter in addition to a back up kick starter. The hardware related to the rear brake is housed in the swing ram. These kinds of engines are understood to be one of the most fuel efficient varieties. With a minimum time to take off these kind of carburetors can hold the speed of the motor scooter till a large extent. This often prevents road accidents. Thus safety and security is ensured through a long term usage of such technically compatible engines in the long run.

GY6 carburetors are very popular and technical make of the engine is a hot favorite amongst motor scooter drivers. With an average life span of 5 years such engines make your journey comfortable.
