The s-step Adams–Bashforth method has order s, while the s-step Adams–Moulton method has order + (Hairer, Nørsett & Wanner 1993, §III.2). These conditions are often formulated using the characteristic polynomials ρ ( z ) = z s + ∑ k = 0 s − 1 a k z k and σ ( z ) = ∑ k = 0 s b k z k . {\displaystyle \rho (z)=z^{s}+\sum _{k=0}^{s-1 ...
The Swashplate engine with the K-Cycle engine is where pairs of pistons are in an opposed configuration sharing a cylinder and combustion chamber. A Delta engine has three (or its multiple) cylinders having opposing pistons, aligned in three separate planes or 'banks', so that they appear to be in a Δ when viewed along the axis of the main-shaft.

Explicit multistep methods can never be A-stable, just like explicit Runge–Kutta methods. Implicit multistep methods can only be A-stable if their order is at most 2. The latter result is known as the second Dahlquist barrier; it restricts the usefulness of linear multistep methods for stiff equations. An example of a second-order A-stable ...
Straight-seven engine with firing order 1-3-5-7-2-4-6. A straight-seven engine or inline-seven engine is a straight engine with seven cylinders. It is more common in marine applications because these engines are usually based on a modular design, with individual heads per cylinder.
The 2.7 L; 167.0 cu in (2,736 cc) EER version debuted in 1998 and is built in Kenosha, Wisconsin. It is a DOHC 24-valve design. Bore and stroke is 86 mm × 78.5 mm (3.39 in × 3.09 in). It is an aluminum block with cast-iron cylinder liners and aluminum heads. Output has varied depending on the application but typical was 200 hp (149 kW) at ...
The Hyundai Delta family is the company's smaller V6 engine, ranging from 2.5 to 2.7 L (2,493 to 2,656 cc). Both share the same 75 mm (2.95 in) stroke and both are DOHC designs. 2.0L (G6BP)
Boxer crankshaft configuration. Most flat-twin engines use a boxer configuration for the crankshaft and are therefore called "boxer-twin" engines. In a boxer-twin engine, the 180° crankshaft moves the pistons in phase with each other, therefore the forces generated by one piston are cancelled out by the other, resulting in excellent primary balance.
