QG18DE

The 1.8 L (1769 cc) QG18DE was designed for Nissan by Aichi Machine Industry, Japan. It is manufactured both in Japan and the Mexican city of Aguascalientes. Bore is 80 mm (3.1 in) and stroke is 88 mm (3.5 in). The engine is tuned to achieve most of its torque at low revs at the expense of raw power at high revs, making the engine very responsive in day-to-day driving. It has a cast-iron engine block, aluminum DOHC cylinder head, uses MPI fuel injection, forged-steel connecting rods, two single-piece cast camshafts and a cast-aluminum intake manifold. It also features N-VCT (Nissan's Valve Timing Control technology). This engine received the RJC Technology of The Year Award of 2001.

Specifications

• Displacement - 1.8 liters (1769 cc)
• Layout - DOHC Inline-4 (Straight-4) with VVT tech (called NVTC).
• Valves - 16, 4 for each cylinder
• Power - 128 hp (95 kW) @ 6000 rpm
• Torque - 130 lb⋅ft (176 N⋅m) @ 2800 rpm
• Redline - 6500 rpm
• Fuel Delivery System - electronic fuel injection
• Fuel compression ratio - 9.5:1

Emissions Control Devices

• OBDII - Onboard Diagnostic System (codes can be read/erased by a variety of readers, e.g. Actron, blaZt). Nissan Pulsar N16 Models without EuroOBD in Australia do not have OBDII.
• EGR - Exhaust Gas Recirculation
• HO2S - (4) Oxygen Sensors (2 before exhaust catalyst, 2 after) - note a series 2 1.8l has only 2 O2 sensors: 1 pre-catalytic-converter and 1 downstream from it.
• TWC - Three Way Catalyst (2 in exhaust manifold, 1 under car).
• EVAP - Charcoal Evaporative Purge Canister.
• Ignition Timing: 9 degrees BTDC (can be altered +/- 2 degrees using CONSULT-II handheld diagnostic tester, e.g. blaZt).
• Knock Sensor - located on engine block; retards timing if pinging/detonation is detected.
• Heated Throttle Body - heated by engine coolant.

The QG18DE is used in the following vehicles:

• 2000-2006 Nissan Sentra B15 and N16
• 2000-2005 Nissan Pulsar N16
• 2000-2006 Nissan Almera N16
• 2000-2006 Nissan Almera Tino
• 1999-2006 Nissan Primera
