The Honda Odyssey new direct-injection system enables increased torque across the engine full operating range along with higher fuel efficiency. The system features a compact, high-pressure, direct-injection pump that allows both high fuel flow and pulsation suppression, while variable pressure control optimizes injector operation. A multi-hole injector delivers fuel directly into each cylinder (not to the intake port, as in the previous generation Odyssey), allowing for more efficient combustion. The multi-hole injectors can create the ideal stoichiometric fuel/air mixture in the cylinders for good emissions control. Theoretically, a stoichiometric mixture has just enough air to completely burn the available fuel. Based on the operating conditions, the direct-injection system alters its function for best performance. Upon cold engine startup, fuel is injected into the cylinders on the compression stroke. This creates a weak stratified charge effect that improves engine start-up and reduces exhaust emissions before a normal operating temperature is reached.
Exclusive to the Odyssey Touring and Elite trims, LED low- and high-beam headlights provide improved nighttime illumination and visibility compared to contemporary high-intensity discharge (HID) headlights. Six LEDs serve as low beams and three LEDs serve as high beams on each side. Besides improving driver confidence and passive safety, the LED headlights use less energy, helping to enhance fuel efficiency by reducing engine loads. In addition, the LED headlights last up to five times longer than HID headlights and up to 10 times longer than halogen headlights - contributing to less frequent replacement and the associated cost savings. An auto on/off function is also included.
The 2018 Honda Odyssey 3.5-liter V6 engine meets the tough EPA Interim Tier 3/Bin 125 and CARB LEV3/ULEV-125 emissions standards, and is certified to this level of emissions performance for 150,000 miles. Numerous advanced technologies are factors in the emissions performance. The unique cylinder head-mounted close-coupled catalytic converters light off quickly after engine start up, and a 32-bit RISC microprocessor within the Electronic Control Unit (ECU) boosts computing power to improve the precision of spark and fuel delivery. The engine features Programmed Fuel Injection (PGM-FI) that continually adjusts the fuel delivery to yield the best combination of power, low fuel consumption and low emissions. Multiple sensors constantly monitor critical engine operating parameters such as intake air temperature, ambient air pressure, throttle position, intake airflow volume, intake manifold pressure, coolant temperature, exhaust-to-air ratios, as well as the position of the crankshaft and the camshafts.
The 2018 Honda Odyssey incorporates a wide range of halogen and light-emitting diode (LED) exterior lighting features. LED headlights are available for the first time, joining available LED Daytime Running Lights (DRL), available LED side mirror turn signals and LED taillights to provide the brightest and most visually distinctive array of Odyssey exterior lighting yet.
