TECHNICAL FOCUS

Spark plug replacement intervals depend on the technology and materials used during plug manufacture, especially in terms of the electrical and heat corrosion resistance of those materials.

The estimated mileage of standard nickel spark plugs is between 30,000 and 45,000 km, platinum spark plugs around 70,000 km, and double platinum spark plugs more than 80,000 km. The estimated mileage of iridium spark plugs – depending on the thickness of the central electrode and the construction of the ground electrode – ranges from 60,000 km up to 120,000 km

in the case of DENSO Super Ignition Spark Plugs, which feature a protruding ground electrode, like DENSO’s Twin Tip (TT) Spark Plugs.

So when it comes to replacing spark plugs, what should you know?

Construction mattersThe central electrode and construction of the ground electrode both have a huge impact on the combustion process. The smaller the surface area of the central electrode, the lower the voltage required for combustion. In addition, you also have to take into consideration the distance between the electrodes.

The ground electrode is of key importance. In 1974 DENSO developed a ground electrode with a now-familiar U-groove design, allowing more focused sparks on a smaller surface area; increased ignition efficiency. Another way to increase ignitability is the use of precious metal plates welded to the ground electrode.

Lower cost and improved performance?In 2003, DENSO introduced Super Ignition Spark Plugs (SIP) featuring a fine tip on the platinum ground electrode.

Based on this construction, DENSO then developed and introduced Twin Tip (TT) Spark Plugs to the aftermarket; which proved a huge success. DENSO’s TT Spark

Plugs are produced without using precious metals on the electrodes – making their price comparable to Standard nickel spark plugs – and feature a nickel center and a ‘twin’ protruding ground electrode with a slimmer 1.5 mm diameter. The complete TT Spark Plugs range is highly consolidated, comprising 15 part numbers that together offer 87% coverage of the top selling EU car parc. If you are looking for a highly ignitable, high quality, durable spark plugs without the costs usually associated with high performance, choose DENSO TT.

In both of these cases – SIP and TT Spark Plugs – the ground electrode facilitates the optimal use of electricity, to greatly limit energy loss caused by a fall in temperature

TECHNICAL FOCUSDid you know?DENSO After Market’s Iridium Spark Plugs have the world’s smallest 0.4mm diameter centre electrode, delivering super-efficient combustion.

through the ground electrode. This solution also allows for a heavier air/fuel mixture around the spark, resulting in better combustion in the combustion chamber – as well as lower fuel consumption, increased engine efficiency and smooth engine running. In low temperature conditions, start-up performance, response times and initial ignition are significantly reduced.

Gas operated enginesWhat about gas operated engines? The operating temperature in a LPG, CNG or LNG engine is much higher than in petrol engines, as the gas/air mixture burns at higher temperature. This higher temperature, together with increased electrical erosion from alternative fuels, gives a different service lifetime of a spark plug compared with normal petrol engines.

This difference can be quite significant and depends on the vehicle application.

What is more, the ignition voltage required to ignite the LPG gas/air mixture is much higher than to ignite a gasoline/air mixture. In the case of a gas/air mixture, an ignition voltage of 10-15 kV is usually sufficient. LPG engines require higher ignition voltage; approx. 25-30 kV.

The increased voltage and combustion temperature of LPG engines means that the spark plugs used in these engines should be replaced more often.

It is therefore recommended to use iridium spark plugs with platinum ground electrodes in gas operated engines. DENSO After Market’s Iridium Tough Spark Plug range delivers the highest ignitability

available in the market, featuring a 0.4mm iridium centre electrode in combination with four times the lifetime of a normal nickel plug. In terms of coverage, DENSO has the highest Iridium coverage for LPG in the market which is around 90% of the popular car parc.

DENSO TT Spark PlugsIn regions where LPG systems are fitted on older car parc, the price is often more sensitive than having the very low replacement rate of Iridium plugs. DENSO then has the extremely effective alternative to Iridium Tough plugs, the DENSO TT Spark Plugs. These plugs compensate for the required higher ignition voltage with a smaller diameter centre and ground electrodes when using alternative fuels.

DENSO TT Spark Plugs provide greater ignitability than platinum spark plugs, and their hardened ground electrode is more resistant to temperature and electrical erosion than standard nickel plugs. This makes the use of TT in LPG engines highly effective for an affordable price.

EGR Valves and EGTSEGR Valves and EGTS are part of DENSO’s Engine Management Systems (EMS) ranges featuring original DENSO technologies, but what role do they play in achieving the most advanced EMS?

How they workThe achievement of cleaner vehicle exhaust gas owes much to the quality and efficiency of the Exhaust Gas Recirculation (EGR) Valve. The role of the EGR Valve is to mix the engine’s exhaust gas with the intake air as appropriate for the driving conditions, reducing the concentration of oxygen in the intake air and slowing the combustion speed. As a result of reduced oxygen density during air intake, combustion temperature decreases and lower levels of harmful nitrogen oxide (NOx) are generated.

• A small passageway exists between the intake and exhaust manifolds. This is where the Exhaust Gas Recirculation (EGR) Valve is located, where it adjusts the amount of recirculated exhaust gas back into the intake manifold

Types:

• Step motor type

• Solenoid type

• DC motor type

Features and benefits:

• Responsiveness: Optimal exhaust gas flow adaptation for all engine temperatures and driving conditions

• Precision: Integrated position sensor allows more accurate control of exhaust gases, resulting in a higher level of precision

• Durability: Reduction in the effect of exhaust pressure and exhaust flow provides carbon corrosion resistance and longer life

• Emission reducing: Reduced NOx emissions.

TECHNICAL FOCUS

EXHAUST GAS RECIRCULATION VALVES

EGR Valve Mounting Location

• When the engine is idling, the EGR Valve is closed and there is no EGR flow into the intake manifold. The EGR Valve remains closed until the engine is warm and operating under load. As the load and combustion temperature start to increase, the EGR Valve is opened and begins to send exhaust gas back into the intake manifold

• Due to the technological advances achieved in EGR control and catalyst technology, cleaner exhaust has been achieved even under lean-burn conditions

The ECU judges information detected by the sensors due to each driving condition. The EGR valve is then opened/closed to

TECHNICAL FOCUS

EXHAUST GAS TEMPERATURE SENSORSHow they workThe Exhaust Gas Temperature Sensor (EGTS), which is located in front of the Diesel Oxidation Catalyst (DOC) and/or in front of the Diesel Particulate Filter (DPF), detects exhaust gas temperature, converts it into a voltage and feeds that voltage signal back to the engine ECU, in order to control engine conditions and effectively reduce emissions.

Due to the improved temperature detection achieved by the EGTS, post combustion fuel injection is closely controlled and the amount of particulate matter in the DPF is accurately estimated – allowing effective ‘regeneration’ of the DPF. This results in cleaner emissions and increased fuel efficiency, as less fuel is required in the DPF regeneration process. In addition, the temperature of the catalytic converter is controlled, protecting it from overheating and reducing deterioration of the catalyst.

draw exhaust gas into the intake air, thereby decreasing the concentration of oxygen in the intake air and slowing the combustion speed. As a result, combustion temperature decreases, thereby controlling the generation of harmful nitrogen oxide (NOx).Due to the advances achieved in EGR control and catalyst technology, cleaner exhaust has been realised even under lean-burn conditions.

• Increasing the EGR volume lowers NOx production to a point, but excessive EGR volume causes incomplete combustion, raising the particulate levels. Achieving the opposing goals of lower NOx production and lower particulate levels requires carefully tuned EGR levels.

• DENSO uses electronically controlled EGR valves that operate in tandem with an electronic throttle.

EGTS• 11 part numbers, covering 46 OE part numbers, 211 vehicle

applications and more than four million vehicles

• Product range covers BMW applications exclusive to DENSO

• Precise monitoring of engine function, thereby enabling higher engine performance with lower emissions and lower fuel consumption

• Highly responsive, yet small and compact

• Able to detect temperature ranges from - 40°C to 1000°C, detecting temperatures within ±10° of the actual temperature. Less than 7 seconds to change from room temperature to 1000°C

• The single tube structure of DENSO’s EGTS is 90% smaller than conventional models, whilst providing the highest responsiveness

• Can withstand vibrations even near the engine

• Products available by responsiveness, and by ability to detect temperature.

EGR Valves• 6 part numbers, covering 51 vehicle applications and more

than 2 million vehicles

• Range includes three types of valves: Step motor type, Solenoid type and the DC motor type

• DENSO is the only brand to offer genuine OE, EGR Valves for selected applications e.g. Toyota Corolla

• Advanced DENSO OE technology ensures optimal exhaust gas flow adaptation and reduced NOx emissions for all engine temperatures and driving conditions

• An integrated position sensor allows more accurate control of exhaust gases and therefore a higher level of precision

• Extremely durable: reduced effect of exhaust pressure and exhaust flow, provides carbon corrosion resistance and longer life.
