Nissan TD42 is a 4.2-liter inline-six diesel engine manufactured by Nissan between the late 1980s and somewhere in the mid-2000s. It falls under the TD series of engines and most commonly fitted in the Nissan Patrol, particularly in harsh weather conditions where reliability is given topmost priority over anything else.
