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.
Odyssey EX and above trims include power sliding side doors that can be activated by a switch (to operate left, right or both doors) on the instrument panel, by a switch from the second-row seating area, by pulling on either the interior or exterior door handle, or by buttons (left or right) on the remote key fob. The system features improved operating logic. In the previous Odyssey generation, if the driver and a passenger outside the vehicle were to each activate a power side door at approximately the same time, the door could start to open with the first person action, and then stop as soon as the second person took action. To eliminate this on the 2018 Odyssey, new door logic enables the door to operate as intended if two identical activations (such as the driver and a passenger both wishing to open a door) are entered within a half second of each other. For instance, if a parent pulls up to the curb at school and presses the power side door open button at approximately the same time as does a child waiting curbside, the door will open as desired. If longer than a half second passes between activations, door operation will stop, and a warning beep will sound.
The strength of the "tailgate ring" (the circular metal structure surrounding the tailgate) is vitally important for superior vehicle handling, stability and ride quality. Debuting on the 2016 Honda Pilot and applied to the 2018 Odyssey for the first time, this advanced tailgate ring contributes to the new model gain in torsional rigidity, benefiting ride, handling and NVH. For the first time in the Odyssey, body stiffness is enhanced using structural foam inserts in key locations. These include the left and right C-pillar stiffeners, and within an inside bracket that connects the left and right side center frames under the front floor. The improved body stiffness pays dividends in handling precision, ride quality, NVH and crash safety.
New on the 2018 Honda Odyssey are center door rails hidden under the rear side glass that replace the visible rails located on the body sides behind the rear doors on the second- through 4th-generation Odyssey. The result is a clean, seamless appearance for the rear body side and no visible side door rails or components. A safety latch prevents the left-hand sliding door from opening when the fuel lid is open. Like the front doors and tailgate, the side doors feature full 360-degree seals to reduce wind and road noise, water and debris from entering the vehicle.
