The firing order of older big-block engines is 1-8-4-3-6-5-7-2 [62] while Vortec 8100's firing order is 1-8-7-2-6-5-4-3. Other upgrades of Vortec 8100 include a new 18-bolt head bolt pattern, longer connecting rods, different symmetrical intake ports, different oil pan rails, and the use of metric threads throughout the engine.
Other planned improvements would target throttle lag, caused by accelerating the gasifier turbine to peak speed, and lack of engine braking. [ 20 ] GT-304 (1956) was the first GM gas turbine to include a regenerator, which used exhaust heat to warm intake air, improving fuel consumption to 0.77 lb/hp·h. [ 18 ]
The LLV (also called Vortec 2900) is a 2.9 L; 178.3 cu in (2,921 cc) straight-4 DOHC engine produced between 2007 and 2012, with a 95.5 mm × 102 mm (3.76 in × 4.02 in) bore and a stroke. It replaced the LK5 and produced 185 hp (138 kW) at 5,600 rpm and 190 lb⋅ft (258 N⋅m) of torque at 2,800 rpm.
The Vortec 5700 L31 (VIN code "R") is a 5.7L V8 truck engine. It is Chevrolet's last production first-generation small-block. The cylinder heads feature combustion chambers and intake ports very similar to those of the LT1 V8, but lacking the LT1's reverse-flow cooling and higher compression.
The Quad 4 underwent two rounds of exhaust port size reductions, followed by the addition of balance shafts in 1995 to address its levels of noise, vibration, and harshness (NVH). Further changes were made for the 1996 model year when the engine's bore and stroke were changed, and the engine was subsequently renamed the "Twin Cam".
The Chevrolet 90° V6 family of V6 engines began in 1978 with the Chevrolet 200 cu in (3.3 L) as the base engine for the all new 1978 Chevrolet Malibu.The original engine family was phased out in early 2014, with its final use as the 4.3 L (262 cu in) V6 engine used in Chevrolet and GMC trucks and vans.

This formulation is dependent on the objects causing the field. The field has units of acceleration; in SI, this is m/s 2. Gravitational fields are also conservative; that is, the work done by gravity from one position to another is path-independent. This has the consequence that there exists a gravitational potential field V(r) such that
