Ignition

1. There’s never a good time for your car engine not to start! Successful, fuel-efficient ignition is one of the most important engine functions, yet a common cause of motorist complaint.

2. As a world-leading developer and manufacturer of original ignition technologies, DENSO is the trusted name behind many world-first ignition technologies. This makes us best placed to provide the most advanced and reliable OE quality Spark Plugs, Glow Plugs and Ignition Coils for the aftermarket’s every need; supplying continually updated aftermarket ranges that guarantee optimum engine performance.

3. For petrol cars, we offer one of the aftermarket’s most exceptional, all-makes Spark Plug programmes – with a plug to suit every driving style, car and pocket. Types include Nickel, Double Platinum, Twin Tip (TT), Iridium Power 0.4mm, Iridium Long Life, Iridium Tough 0.4mm, Super Ignition Plug (SIP) and Iridium Racing 0.4mm; many featuring DENSO-patented innovations. We also offer Spark Plugs for a huge range of motorcycle, marine and small engine applications including Nickel and Iridium Power.

4. For diesel needs, our all-makes replacement Glow Plugs range is recognised as one of the best in the industry for scope, coverage and performance. Drawing on our heritage as a world leader in OEM Diesel systems, the programme includes Single Coil, Double Coil, Ceramic and Instant Heating technologies.

5. Our Ignition Coils range also features the same, advanced technologies that we supply to car makers worldwide. From Coil on Plug (COP) and Ignition Coil Block types to Distributor Coils and Stick Coils, each item has been specifically designed by DENSO to deliver optimum performance, energy savings and easy installation.

DIRECT IGNITION COIL  BIẾN ÁP ĐÁNH LỬA TRỰC TIẾP

DENSO 1st

DENSO is a long-standing leader in direct ignition technology, working in close cooperation with vehicle manufacturers around the world. We developed the car industry’s first, compact, stick-type ignition coil. DENSO also pioneered micro-sized driver circuits and diagonal inductive windings for improved performance in a smaller space. These design breakthroughs, and others, feature in DENSO’s Ignition Coils for the aftermarket, ensuring reliable, efficient ignition performance on every journey.

The DENSO Difference

In today’s low emission, high-efficiency engines the key to effective combustion is consistent, high-energy ignition output. The high voltage required for ignition is provided by the Ignition Coil – a type of transformer that features primary and secondary coils of wire wrapped in layers around an iron core. The role of the Ignition Coil is to transform the low voltage in a car’s battery into the thousands of volts which are used by the spark plug to generate sparking. These sparks ignite the air-fuel mixture inside the combustion chamber.

High-Energy Ignition Output

A leader in direct ignition technology, DENSO developed the auto industry’s first compact stick – type ignition coil. The space-saving design, since adopted by many of the world’s leading automakers, requires no high-tension ignition cable, fitting neatly into the engine’s spark plug bore. Along with its stick coil technology, other advanced features pioneered by DENSO include micro-sized driver circuits and diagonal inductive windings. In the development of today’s high-tech ignition systems, the automakers and DENSO are full partners.

That same expertise is put to use on all DENSO ignition coils regardless of their configuration. Each DENSO ignition coil is designed and optimized for its specific application, then continually improved by DENSO’s global engineering team for maximum performance. One key to effective combustion in today’s low-emission, high-efficiency engines is consistent, high-energy ignition output. DENSO direct ignition coils deliver it.

1. Driving Circuit: DENSO has developed a small-size integrated driving circuit into the top of the coil.

2. Superior Quality Components & Materials to ensure optimal performance.

3. Tested & Inspected to ensure high quality.

4. Diagonal Windings to eliminate sectioned bobbins, reducing size and weight.

Features and Benefits

Small size, lightweight

– Innovative, small-size driving circuit is integrated into the top of the coil

– Cylindrical ignition coil can be installed in the plug hole, saving previously ‘dead’ space

Energy saving

– The coil’s improved magnetic efficiency generates a high voltage faster

 Highly reliable

– Advanced design ensures reliable high temperature, suppresses noise and eliminates phantom misfires

– Only superior materials are used for top quality and reliability

Easy to install

– Integrated igniter eliminates the need for high tension ignition wires, so easier to install

Characteristics

How ignition coil works

In the past, ignition systems used a spark distribution system in which the high voltage generated by an Ignition Coil was distributed to the spark plugs by a distributor. Today’s engines feature a Distributor-Less Ignition (DLI) system, delivering high voltage directly from the ignition coils to the spark plugs. For engines with an electronic ignition system, DLI systems create a high voltage by using a coil with an igniter (Stick Coil) that is directly mounted onto the spark plugs in the cylinders.

The Ignition (Stick) Coil is a type of transformer, consisting of:

a primary coil that changes electrical energy into magnetic energy.
> a core (iron) that acts as a magnetic circuit to accumulate magnetic energy.
> a secondary coil that converts magnetic flux variations as electrical energy into high voltage.

Installation and Fault Finding

Removal and installation

1. Disconnect the connector from the faulty Ignition Coil. Remove the screw(s) and faulty Ignition Coil.

2. Install the new Ignition Coil into the plug hole of the cylinder head in the same orientation with the original sensor, in order to secure the connection to the spark plug terminal. Install the screw and connector. Turn the engine on and check if the ignition system works properly.

3. Pay extra attention when connecting the Ignition Coil to the spark plug. Misalignment can cause severe spark plug damage.

 

Fault finding

Possible failures 

Ignition coils can fail before their usual service life due to wear and defects such as overheating caused by internal short circuits, defective ignition cables, low battery power, vibration, thermal failures, mechanical damage and incorrect contacts.

Symptoms 

– No combustion: No combustion occurs because no spark is emitted.

– Stalling: Engine stalls but can be restarted.

– Poor drivability: Hesitation during acceleration or the engine misfires.

Prevention and Solutions 

– The Diagnostic Trouble Code (DTC) engine warning light will probably be turned on, indicating an ignition error – however, this might be caused by another system problem. A visual check should therefore be performed first. Check for any mechanical damage, such as cracks and carbon tracks on the Ignition Coil body, any corroded or worn plugs and cables in the wiring, any loss in battery power to the ignition system, and any oil or water contamination.

– If an ignition coil is identified as defective, the root cause should be determined with care, to avoid the replacement Ignition Coil failing just like the original Ignition Coil. The vehicle manufacturer’s ignition system instructions should always be referred to in the first instance.
