Technical Information

BRISK offers several types of spark-plugs that can be fitted in most spark-ignition engines.

They comply with engine requirements and are designed to be used with prevailing types of operation of motor vehicles and the character of their users. You can choose from either matching equipment or equipment in individual series in our catalogue. At the same time, we also introduce a marking system for BRISK spark-plugs.

A spark-plug is a device placed in cylinder heads in internal combustion engines, functioning on the principle of spark-ignition of a mixture of air and fuel. The spark-plug is connected to the cylinder head by means of a thread. The active part protrudes into the engine's combustion chamber. Its upper part is used to secure a high-voltage supply from the vehicle's ignition system to the spark gap of the spark-plug. The basic function of a spark-plug is ignition of the air and fuel mixture in the engine's combustion chamber at a precisely defined time.

Unique and Patented Design

Higher output, better throttle response and acceleration are achieved through better fuel energy utilization. This in turn also lowers the exhaust emission.

Completely New Spark Gap Shape

Brisk's design provides an unrestricted and more spontaneous spread of the flame front which is achieved by:

Spark Gap Deep in Combustion Chamber

Shifting the spark gap deeper inside the combustion chamber provides better access of the air fuel mixture to the point of ignition. Since the flame front propagates evenly in all directions the best place for ignition is in the center of the combustion chamber. The compact design of the spark gap minimizes turbulence and therefore increases the volumetric flow.

Integrated Ground Electrode

The massive ground electrode is the integrated part of the spark plug shell which provides superior heat removal from the active part of the spark plug, improving the resistance to pre-ignition and electrode burn-off. Ionization and spark-over occurs automatically together with an optimum composition of the fuel/air mixture. The spark plug gap is not shielded by the side electrode, so the mixture has unlimited access. Better mixture ignition, and thus higher combustion speed, and faster flame front spread, especially at the beginning of combustion, allows better fuel energy utilization. The subsequent increase in medium effective pressure in the engine cylinder and balancing of values of medium effective pressure during individual working cycles contribute to increased engine power.

Measurements made for example of CHEVROLET SUBURBAN 5.7 l and VW GOLF, performed by an independent testing authority in Canada, confirm comparability of both designs.
