Assistant: The 3S-GE is a naturally aspirated, in-line 4-cylinder 2.0-liter DOHC 16-valve engine in the Toyota Celica, particularly used in the ST162 model. Here are key details about the 3S-GE engine relevant to your interest:
– It has a cast iron block with aluminum alloy cylinder head, with bore and stroke dimensions of 86mm x 86mm, giving a total displacement of 1998cc.
– The engine uses a cross-flow type cylinder head with pent-roof combustion chambers, and the spark plugs are centrally located in the combustion chamber.
– This engine employs Toyota’s Variable Induction System (T-VIS) in some versions to improve torque at low and mid engine speeds.
– Compression ratios may vary by generation and market version, with earlier versions around 9.2:1 to 10.1:1, and later “BEAMS” versions going up to 11:1 or higher.
– Power output in the 1986 ST162 Celica was about 96 kW (approximately 129 hp) at 6000 rpm with 147 Nm of torque at 5200 rpm.
– The ignition order is 1-3-4-2, with a single timing belt driving the dual overhead camshafts, supported by five cam journals, and valve clearance adjustment done by outer shims.
– Pistons are aluminum alloy with full-floating piston pins. The crankshaft is supported by five aluminum-alloy bearings and is counterweighted for balance.
– In the ST162 Celica, the 3S-GE is mounted transversely in a front-wheel-drive layout and used with a transaxle.
The 3S-GE is regarded as a higher output variant compared to the 3S-FE (economy version) and lacks the turbocharging of the 3S-GTE version used in the ST165 Celica GT-4. It has a reputation for being a durable and performance-capable engine rivaling similar 2-liter Japanese engines of its era.
More advanced versions of the 3S-GE evolved over the years, including the third-generation with up to 132 kW and later BEAMS versions with variable valve timing delivering even higher outputs. However, within the ST162 Celica generation, the 3S-GE is the naturally aspirated 2.0L DOHC engine optimized for a balance of performance and reliability.
If you want information on specifics like timing, valve clearance, or ignition timing procedures, I can provide those technical details from the service documentation as well.
Let me know if you’d like deeper explanation on any particular aspect of the 3S-GE engine, its service, or performance characteristics in the Celica ST162 or comparable models.
Summary:
– Inline-4, 2.0L DOHC 16V engine
– Iron block, aluminum head, 86x86mm bore and stroke
– VVTi and T-VIS used in later generations
– 96 kW/147 Nm in early ST162 application
– Transverse, FWD transverse layout with transaxle
– Ignition order 1-3-4-2, timing belt driven cams
– Durable, performance-oriented compared to 3S-FE or 3S-GTE turbocharged versions【4:0†st162-forum-posts-merged-02.txt】 【4:1†st162-forum-posts-merged-02.txt】
