Especially when working with mechanical ignition systems, it’s crucial to understand ignition coil charge-up and dwell time. This guide will give you everything you need to know about how charge-up works for different ignition systems and engine speeds – and how common ignition problems can arise.

All ignition systems for modern petrol engines use ignition coils for the same basic function: to create the high voltage required to produce a spark at the spark plug. Aftermarket professionals will be familiar with their purpose and basic attributes – but they may not know about the in-depth scientific principles they rely on.

Sébastien Ogier and co-driver Julien Ingrassia became only the second ever team to win 50 FIA World Rally Championship stages, scoring a memorable victory at Rallye Monte-Carlo. After a challenging race in icy conditions, Ogier topped the podium ahead of Elfyn Evans and Scott Martin in a TOYOTA GAZOO one-two.

It’s not an easy time to run an independent garage. Restrictions brought about by the global Coronavirus pandemic and a wholesale transition towards new vehicle technologies are bringing about multiple challenges for independent workshops.

In the automotive aftermarket, new technologies and trends are arising at a faster rate than ever before. Amid this background, even the most experienced technician might worry about how relevant their skills will be in a few years’ time. But don’t despair – keeping your skills up-to-date is easier than ever, thanks to the proliferation of training courses, many of which have headed online. Nick Thomas, DENSO Project Sales Manager, discusses how to find the right course for you and where the training movement will go next.

The basics of a glow plug are easy to explain. They are essential for ignition in diesel-powered engines (as opposed to spark plugs in petrol engines); they heat the air/fuel mixture in the engine so it ignites easily under compression; they are built to be long-lasting and work reliably no matter what happens. However, occasionally external factors or faults with other components can lead to issues with glow plugs. Owing to their rarity, these can easily be missed or wrongly identified.

Sébastien Ogier and his co-driver Julien Ingrassia came from behind to win the FIA World Rally Championship after a dramatic final stage at Monza. Ogier overhauled his Toyota GAZOO stablemate Elfyn Evans on the final stage to take his seventh WRC title in eight years and his first with Toyota GAZOO Racing, sponsored by DENSO.

Spark plugs play a critical role within the ignition system of petrol vehicles, with two main functions. One is to ignite combustion to start the engine and the other is to move heat away from the combustion chamber.

The winners of the 2020 edition of the League of True Mechanics have been announced! The list of winners can be found in this article and is also available after login in the “Hall of fame”.

TOYOTA GAZOO Racing’s #7 TS050 HYBRID, sponsored by DENSO and driven by Mike Conway, Jose Maria Lopez and Kamui Kobayashi, has won the 2020 FIA World Endurance Drivers’ Championship. By winning the final event of the season in Bahrain, they narrowly beat their teammates Brendon Hartley, Sebastien Buemi and Kazuki Nakajima to the top spot.
