DENSO provides the spark to energise the ride!
It might be small and seem unimportant, but the spark plug is a key component within a motorcycle’s ignition system, as it’s what generates the spark needed to ignite the air-fuel mixture in the combustion chamber, powering the engine. The more efficient the process, the better the performance, fuel economy, and reliability of the machine.
As the ambient temperature can have a significant effect on engine performance, it is important that everything within the owner’s control is operating correctly and that means making sure their machine is properly and thoroughly maintained, as that includes the spark plugs, a vital component that many overlook.
How does heat affect spark plug performance?
Increased engine heat: Hot weather raises engine temperatures, which can lead to pre-ignition or ‘knocking’ if the spark plug isn’t functioning optimally
Fuel vaporisation: Higher ambient temperatures can cause fuel to vaporise more quickly, affecting combustion efficiency
Carbon deposits: Excessive heat can lead to incomplete combustion, resulting in carbon deposits on the spark plug, so reducing its ability to ignite the air-fuel mixture effectively
Therefore, selecting the correct spark plug for warm conditions ensures engine performance is optimised and prevents those heat related issues. However, what are the factors to consider?
First, spark plugs come in heat ranges that represent their ability to dissipate heat away from the tip of their electrode. A colder plug does this more quickly than a hotter plug, which could make it a better option in areas with a high ambient temperature, but this is also good for high performance engines. Furthermore, a plug of the wrong heat range can cause serious engine damage, so selecting one of the correct heat type is therefore, crucial.
Second, DENSO spark plugs are available in three types of materials: nickel, platinum or iridium, each offering distinct performance characteristics that suit different engine requirements and riding conditions.
Nickel spark plugs are a cost-effective solution for standard performance engines, as they provide reliable ignition and are therefore suited for everyday use. However, they have a shorter service life compared to platinum or iridium plugs.
Platinum spark plugs feature a platinum tipped centre electrode, which increases wear resistance and extends service intervals, which is ideal for riders looking for lasting performance.
Iridium spark plugs use an ultra-fine iridium alloy centre electrode for maximum ignition efficiency, durability and high temperature resistance. They are therefore, the optimal choice for high performance engines and demanding riding conditions, particularly in hot weather.
In summary, choosing the right DENSO spark plug ensures optimal combustion, improved fuel efficiency, and consistent engine performance, throughout the riding season.
DENSO’s motorcycle spark plug range features the most advanced technology available for motorcycle engine ignition, guaranteed by its commitment to research and development and its pioneering innovation at the highest level of motorcycle motorsport.
Using its patented Iridium alloy, DENSO’s Iridium Power spark plugs are extremely durable, wear resistant and can withstand the most extreme conditions. In addition, the leading U-groove ignition technology in these spark plugs generates a stronger spark and increased ignitability for improved power output and reduced fuel consumption, which ensures that Iridium Power spark plugs provide the ultimate in spark performance, making them the summer spark plug of choice.
