7 NGK and NTK products are designed solely for use in automotive, motorcycle, marine, horticultural, agricultural, commercial, industrial, and stationary engines. NGK and NTK products should not be used in aircraft engines. Resistor spark plugs should always be used where they are recommended by the manufacturer. The use of non-resistor plugs could, in some cases, result in interference with and/or damage to electronic components. NGK and NTK products listed in the application guides do not apply to racing or modified engines, except where explicitly stated. 1. SPARK PLUG DESIGN. SPARK PLUG DESIGN. Wide gap Twin ground Every year the range of NGK spark plugs grows to accommodate the ever increasing demands of modern engines. Spark plug design must take into consideration many features of an engine including physical dimensions, combustion chamber shape, cooling abilities, fuel and ignition systems.

8 Spark plugs play a vital role in producing the maximum power from an engine whilst keeping fuel consumption and BPR5ES-13 BKR6EK. emissions to a minimum. Choosing the correct spark plug type will help a vehicle manufacturer meet legislated emission targets and assists the motorist in getting the best from their engine . Three ground Four ground Increases in the size and the requirement to improve the cooling of the inlet and exhaust valves have meant that the space available for the spark plug is severely restricted on some cylinder heads. A. change in spark plug design, possibly the adoption of a taper seat and extended reach (threaded portion) or even the use of a smaller BCP6ET BKR6 EQUP. diameter is often the answer. Some engines require the use of two spark plugs per cylinder and again due to space restrictions these Extra projected might be of different sizes. Precious metal and shielded Changes in fuelling systems and the fuel itself have meant some special features being adopted at the firing end' of the spark plug.

9 Extra projected types push the spark position into the heart of the combustion chamber to promote better combustion of the fuel/air mixture, which is weaker than ever in an effort to improve economy. Modern engine ZFR6E-11 IZFR6B. manufacturers often require increased spark gaps to allow a longer spark duration, which again aids more efficient combustion. To combat the cold fouling' effect that can occur in some engines using unleaded fuels specially arranged ground electrodes are sometimes used. These can force the spark to discharge across the insulator and thus burn away any built up carbon that could cause poor starting or misfires. It is not uncommon to find two, three or four ground electrode arrangements in new vehicles. The use of precious metals on the tips of the spark plug electrodes is not uncommon especially on higher performance engines. Whilst these spark plugs do have increased service life they are often specified because of their superior ignition qualities.

10 Our engineering departments work very closely with the engine and vehicle manufacturers to produce the ideal spark plug type for each application. Any change in production is expensive for a manufacturer and therefore new spark plug types are only produced where necessary. NGK employ the very latest production technology to ensure that every aspect is catered for performance, economy and value. HEAT RANGE AND HEAT DISSIPATION. Spark plugs do not produce heat in the combustion chamber. One of the functions of the spark plug is to dissipate some of the heat produced during combustion. This is mostly transferred into the cylinder head. The 'Heat Range' indicates the measure of the spark plug's ability to do this. A 'hot' spark plug is designed to maintain a sufficiently high temperature at the insulator nose to burn off carbon and oil deposits. A 'cold' spark plug is designed to allow a faster transfer of heat to the cylinder head thus preventing overheating and premature failure.
