Similar to U engines, H engines consist of two separate flat engines joined by gears or chains. H engines have been produced with between 4 and 24 cylinders. An opposed-piston engine is similar to a flat engine in that pairs of pistons are co-axial but rather than sharing a crankshaft, instead share a single combustion chamber per pair of ...
Other manufacturers may modify the engine after it has left the Toyota factory but the engine still keeps the original Toyota designation. For example, Lotus added a supercharger to the 2ZZ-GE in some versions of the Lotus Elise and Exige, but the engine is still labelled 2ZZ-GE, not 2ZZ-GZE. Examples: 3S-GTE 3S – Third model in the S engine ...
The engine block is the same as the naturally aspirated 1NZ-FE engine, found in many Toyota models. It retains the same 10.5:1 compression ratio as the naturally aspirated sibling. Output is 143–152 PS (105–112 kW; 141–150 hp) at 6000 rpm with 196–206 N⋅m (145–152 lb⋅ft; 20–21 kg⋅m) of torque at 4000–4800 rpm.
The letters of the model code is found by combining the letters of the engine code with the platform code. If the engine code and the platform code have two letters each, the middle letter is computed according to this formula: [ 1 ] [ 2 ]
The Toyota PCM electronically limits RPM to about 8,200 RPM via fuel and/or spark cut. The "lift" engagement and the engine redline vary by application. Lotus 2ZZ-GEs are rev limited to 8,500 RPM, for example, whereas Celicas were rev limited to 7,900 to 8,200 RPM in North America, depending on the model year.
Output for this engine is rated at 132 hp (98 kW) at 6400 rpm and 118 lb⋅ft (160 N⋅m) of torque at 4400 rpm for most applications. Compression ratio has been increased to 10.7:1, red line is at 6600 rpm. VVT-i varies the intake valve lift between 1 and 11 mm (0.039 and 0.433 in) according to load and RPM. [1] [2] Specifications
The 1.8L model with the 1ZZ-FE engine was ceased and was replaced with the 1.6L model with the 1ZR-FE engine producing 122 bhp. The facelift Altis was launched in May 2011. The Altis comes with wood grain panel inserts in the interior, optitron speedometer, 5-spoke alloy rims, fog lamps, power windows, power seats, ABS with EBD, driver side SRS ...
The fuel-injected version referenced above was denoted as the Z24i (Throttle Body Fuel Injection) and was first available in the Nissan Model 720 ST pickup during the 1985 model year and was replaced in 1990 by the KA24E engine and they share the same bellhousing pattern. Beside the fuel-injection, a significant change for the Z24i was the ...
