The Mazda K-serial motorca engine is a short stroking 60° 24-valve V6 with belt-driven DOHC and all-aluminium construction. Displacements range from 1.8 L to 2.5 L. They all use a 27-degree DOHC valvetrain with directly motivated hydraulic bucket lifters. The K-serial publication likewise features a extremely rigid atomic number 13 split-crankcase engine block purpose with 4-decamp mains with extra bolts securing the lower block, an internally counterpoised imitative blade crankshaft with lightweight pulverization forged atomic number 6 steel connecting rods. They were organized with the intent of being as compact as possible for short-hood front-roulette wheel drive applications.
One unique innovation of the K-series was the introduction of Variable Resonance Induction System (VRIS). Based on the Helmholtz resonance principle, the intake manifold paper is equipped with 3 chambers tuned to a specific resonant frequency. The computing machine dynamically switches 'tween each resonant bedroom to achieve the seize resonant frequency for the engine's rpm. This effect optimizes volumetrical efficiency terminated a given rpm range to leave maximum torque over the entire revolutions per minute range. VRIS is old on the K8, KF, and KL but almost all modern Mazda V6s are now using this engineering.
The K-series totally throw a 7,000 rpm redline with 7500-7800 rpm clipper, which given the engine figure is conservative. The KJ-ZEM Miller cycles/second engine had a 6,000 rev redline, but was only useable with an self-moving transmission.
K8 [edit]
The 1.8 L (1,845 cc) K8 is among the smallest production V6 engines ever; and too the first K-series engine to be used in a Mazda car (in the Mazda MX-3). Information technology was a DOHC 4-valve design with VRIS and a bore and stroke of 75 mm × 69.6 mm (2.95 in × 2.74 in). It produced 130 hp (97 kW; 132 PS) in US trim (sometimes referred to As "K8-DE"), and 135 hp (101 kW; 137 PS) in Asian country trim (the "K8-ZE") on introduction in 1991 and 144 hp (107 kW; 146 PS) and 115 pound⋅ft (156 N⋅m) at its outflank. The displacement reaction was held under 2000cc to minimize the annual Japanese road tax obligation.
Applications:
- Mazda Mx-3
- Eunos 500
KF [edit]
- 2.0 L KF - 2.0 L (1,995 cc) 78 mm × 69.6 mm (3.07 in × 2.74 in) bore and stroke - The 2.0 L KF engine was available in various states of tune. The KF-DE produced 140 hp (104 kW; 142 Postscript) and 132 lb⋅ft (179 N⋅m) and later on 144 hp (107 kW; 146 PS) and 132 lb⋅foot (179 N⋅m). The JDM version KF-ZE engine produced 160 horsepower (119 kW; 162 PS) and 132 lb⋅ft (179 N⋅m). The Lantis Typecast R version produced 170 hp (127 kW; 172 Postscript) and 140 lb⋅foot (190 N⋅m).
KJ-ZEM [edit out]
The 2.3 L (2,255 cc) 80.3 mm × 74.2 millimeter (3.16 in × 2.92 in) bore and stroke, KJ-ZEM was unrivaled of Mazda's most technologically high engines. It employs the "Miller cycle" which uses a supercharger to increase compression efficiency by decreasing the compression losses (i.e., flywheel energy accustomed contract the uptake charge in the cylinder); and thereby increasing the net ability output of the V6. It was used in the T-platform cars. The supercharger used is the twin-screw type with electronic boost control. Index output was 217 hp (162 kW; 220 PS) and 210 lb⋅ft (285 N⋅m). The KJ-ZEM was happening the Ward's 10 First Engines list for 1995 through with 1998.
Applications:
- Mazda Millenia S
- Eunos 800
- Mazda Xedos 9
KL [delete]
The 2.5 L (2,497 cc) KL family uses an 84.5 millimetre × 74.2 mm (3.33 in × 2.92 in) dullard and cerebrovascular accident. It includes the Japan-only KL-ZE, which produced 200 H.P. (149 kW; 203 Postscript) and 165 lb⋅ft (224 N⋅m). Another variant, the KL-Delaware (alias the KL-03 outdoors the US, and fitted to 2.5-litre Ford Probes) was the worldwide translation, with 164–174 bhp (122–130 kW; 166–176 PS) in various applications. In 1998 a altered version of the KL known as the KL-G4 was used in the 626. It featured solid lifters, a cast crankshaft to reduce rotating mass and a reworked intake system. The distributor was replaced with a Ford EDIS coil-pack ignition.
Mazda introduced a key technology with these engines, known as the Covariant Resonance Installation System (VRIS). A series of two butterfly valves coupled with electronically dominated actuators varied the intensity and length of a resonating chamber inside the intake manifold. The valves set off at particular engine frequencies (i.e. rpms) to garden truck optimal torsion/H.P. yield at any given locomotive engine rush. The valve operates to create three specific first-order resonant frequencies that increase cylinder strain kick. All three resonances are used from 0 to 6250 rpm (6800 for the KL-ZE). Above that threshold, the first primary resonant chamber is again used, but at this engine speed the insistence wave from the second-say resonant frequency aids in charging the cylinder.
Applications:
- KL-Delaware
- 1993-1997 Mazda MX-6 LS (A specification)
- 1993-1997 Ford Probe GT
- 1992-1995 Henry Ford II Telstar TX5 Ghia, TX5 Ghia 4ws
- 1993-1997 Mazda 626 ES, Cardinal (after 1994)
- 1995-2002 Mazda Millenia L
