The throttle limit rule refers to the requirement in some motor racing competitions that the diameter or shape of the car’s air intake (usually where the air enters the engine) must comply with specific regulations. Such rules are designed to limit the amount of air in the engine to ensure some fairness in performance between different cars, but also to control the power output of the engine, ensuring that the competition between different cars is based on differences in driving skills and team engineering, rather than solely on engine performance differences. In the international arena, the engine intake caliber has a specified limit (such as 38mm), but in the Chinese off-road rally arena is not the same. At the beginning, in order to make the domestic racing car with a weak technical base can get up quickly and make the race more exciting, so the Zhongqi motorcycle Federation has almost no restrictions on the size of the engine intake caliber in the technical rules.
Under the rules of the throat limit of the air intake of the racing car, the performance of the engine can not be improved by the intake caliber of the engine, but the special racing fuel with high octane number and high oxygen content can effectively improve the engine performance and reach the best level of the racing car.
Choose Apex racing fuel specifically developed for off-road and rally with higher octane number, higher oxygen content, and no metallic lead for better protection of engine components and oxygen sensors. High octane fuel prevents knocking and provides more power in a high compression ratio engine; The higher oxygen content promotes fuller combustion, as well as a good engine cooling trend, and also ensures better engine reliability in the race, which is very important for off-road and rally racing.
APEX C2D V111 is one such racing fuel that was created for the event, a very high octane, oxygenated, unleaded fuel with one of the highest antiknock indices on the market. Its unique composition ratio scheme can push the boundary between boost pressure and compression rate to the mechanical limit while avoiding knocking. The fuel is mainly used in drift and drag racing, but can also be used in mountain climbing, rally and track racing. High performance racing engines may generate more heat when using high octane fuel, Apex’s V111 fuel, matched with the right oxygen content, provides combustion cooling to avoid mechanical failures caused by overheating, ensuring component reliability and longevity.
While choosing the right fuel is critical to performance, saving fuel is also an important consideration. When the right fuel strategy is adopted, the vehicle needs to be calibrated according to the air-to-fuel ratio of our oil, and the engine tuning and driving strategy need to be optimized to ensure the best fuel efficiency in the race and thus go further. Apex’s international team will work closely with your racing team to select the most suitable racing fuel based on your racing regulations and performance objectives, so that you can achieve the best in the race!
