Electronic Diagnostics Suzuki’s Celerio arrived in 2015 and has been hailed as an affordable, economical and reliable small car. Kim Henson and Edward Haggar take a look at its electronic management system.
Suzuki has been producing effective, economical and durable small engines for many years, with valuable experience gained from the firm’s motorcycles – also cars such as the three-cylinder Alto of the mid-1980s.
The Celerio is powered by a 998cc three-cylinder K10B engine, or, for higher-specification versions, the K10C ‘Dualjet’ motor. The K10B engine is a very efficient unit. When launched, it came with a 99g/km CO2 rating and an official combined mpg figure of 65.7 – though the K10C is better still. It features a higher compression ratio (12.0:1 rather than 11.0:1), plus friction reduction technology, with variable valve timing too. In addition, it incorporates a cooled exhaust gas recirculation (EGR) system and piston cooling jets.
Bowl-shaped combustion chambers are also used to create more turbulence within the cylinders, in conjunction with a dual injection set-up, known as ‘Dualjet’. Versions so equipped are also fitted with Suzuki’s Engine Auto Stopstart System (EASS).
When launched in 2015, the K10cpowered Celerio was the ‘cleanest’ car available in the UK for an on-the-road price of under £10,000, with a CO2 rating of 84g/km and an official combined consumption figure of 78.4mpg.
Although the Thai-built Celerio was classed as a city-car hatchback, all variants feature five doors and five seats, and incorporate greater cabin room and boot space than many rivals.
The car featured here was registered in May 2016 and is powered by Suzuki’s three-cylinder 1.0-litre K10B engine.
Preparation
There’s plenty of room around the engine and it’s an easy unit to look after for a do-it-yourself mechanic. The engine is equipped with a timing chain rather than a belt.
As with Suzuki engines generally through the years, these engines have proved to be very reliable in service.
Changing the oil and filter at least as often as recommended by Suzuki is a good move to maintain reliability and to help extend engine life.
