The proven most efficient turbo diesel in the world receives efficiency updates. Wayne Gerdes – CleanMPG – Aug. 17, 2017 2018 Honda Civic 1.6L iDTEC For European consumption, Honda just introduced a revised 118 hp and 221 lb.-ft. of torque 1.6L i-DTEC turbo diesel I4 powers the 10th gen Civic from zero to 60 in just 10.3 seconds. The revised turbo diesel will be available in the 10th gen Honda Civic beginning in March of 2018. Remember that the current iteration of this engine set a European Circumnavigation Lowest Fuel Consumption Guinness World Record just two summers ago. Honda Civic Tourer Sets Guinness World Record in Europe The new engine is one of the first engines to be tested under the new Worldwide Harmonised Light Vehicle Test Procedure (WLTP) fuel consumption and emissions cycle, which will be a bit more realistic efficiency testing for European consumers. The current New European Driving Cycle (NEDC) test is based on a theoretical driving profile on a dynamometer whereas the WLTP cycle was developed using actual driving data gathered from around the world. It is designed to produce results closer to a real-world driving efficiency the average consumer could expect to achieve. The newly revised engine includes significant improvements to the internals and exhaust system to maximize real world efficiency. The efficiency enhancements result in fuel economy and CO2 emissions of 66.3 mpgUS and 99g/km under the new WLTP cycle. The improvements to the 1.6L i-DTEC turbo diesel include a reduction in cylinder friction thanks in part to pistons made from chromium-molybdebnum steel alloy and ‘super plateau honing’ of the bores to enable smoother piston movement. The 1,597cc engine uses the same Bosch fuel injection system as before, and features a small, high-efficiency turbocharger, low-pressure EGR (exhaust gas recirculation) system and a high-intake flow, high-swirl cylinder head port. A high-strength, lightweight slender crankshaft and all-aluminum, open-deck, high-pressure, die-cast engine block minimize the engine’s weight. For the new i-DTEC, additional cast ribs have been added to the cylinder block to increase structural rigidity and, consequently, improve the management of noise, vibration and harshness (NVH). A new 9-speed AT will further bolster the Civic’s powertrain options in mid-2018, representing its first ever application in a FWD car. Honda’s new 1.6L i-DTEC is also one of the first engines to be officially tested through the Real Driving Emission (RDE) procedure to validate NOx and particulate (PM) emission levels. Instead of a DPF, Honda is using a Lean NOx Trap Cat. The new NOx Storage Converter (NSC) system with larger catalysts and a higher content of noble metals (silver, platinum and neodymium) that store nitrogen oxide gas until the regeneration cycle. A soot sensor accurately detects when the regeneration cycle is required, extending exhaust component durability. Assembled at Honda of the UK Manufacturing in Swindon, the revised engine will be available in both the four-door sedan and five-door hatch 10th gen Civic. 2018 Honda Civic with the 1.6L iDTEC I would, I want!
