Product Description

SINOTRUK HOWO A7 HOHAN Truck T12.42-50 CNG Gas Engine Assembly 420HP Euro V


This heavy-duty 420HP T12.42-50 natural gas (CNG) engine assembly is engineered for Sinotruk HOWO A7, HOHAN NX, and N7G series commercial vehicles, delivering a powerful alternative propulsion core that complies with Euro V emissions. Built with a 6-cylinder inline water-cooled block, electron-controlled gas injection valves, and an advanced high-boost turbocharger, it maintains high-torque mechanical delivery across low-to-mid RPM spectrums. This assembly effectively targets critical powertrain issues like compromised cylinder head thermal stress, erratic spark timing, and progressive low-compression power drops that disrupt operational timelines. Perfect for cross-border eco-logistics supply runs, city-to-city line haul fleets, and high-tonnage mining transit lines, this green-energy engine lowers long-term fuel overheads and secures strict environmental regulatory compliance.

Product Specification


Product Name Gas Engine Assembly
Part Number  T12.42-50
Condition New
Origin China
Quality Standard 100% Tested
Quality Certification ISO, CCC, GSO, CE, SGS, TUV
Weight 980 KG
Dimensions

1450 X 980 X 1250 mm
Lean-Burn Gas Dynamics & Powertrain Safety Upgrade: Engineered with specialized electron-controlled gas fuel injection matrices and an optimized lean-burn combustion system, this engine block ensures immediate, uniform flame propagation across all 6 cylinders. This balanced dynamic layout provides superior thermal efficiency under heavy mechanical loads, preventing local block distortion and maximizing high-load transport safety during long uphill highway distribution.
Alloyed Core Cast Block & Mechanical Durability Overhaul: Manufactured from specialized high-strength structural cast iron alloyed with premium thermal stress-relieved liners, the entire crankcase structure exhibits exceptional tensile properties and fatigue resistance. The robust material composition prevents structural micro-cracking along cylinder walls and prevents main bearing bore warping, delivering a prolonged engine service life that reduces repetitive rebuilding costs.

Turbocharged Water-Cooled Architecture & All-Weather Adaptability: Developed with an intensive impulse turbocharger and a heavy-volume internal water-cooling jacket matrix, this motor provides excellent heat dissipation away from core combustion components. This comprehensive thermal layout maintains cold-start fluid distribution and constant horse-power output during severe summer desert distribution, freezing sub-zero arctic deliveries, or heavily dusty terminal operations.

OEM-Baseline Specification Match & Simplified Installation: Manufactured strictly in accordance with original Sinotruk factory physical dimensions and standardized transmission bell-housing alignments, this assembly guarantees a 100% direct-replacement fit for gas truck chassis. Fleet maintenance technicians can drop the assembly onto existing chassis mounts and connect matching wire clusters instantly without drill re-alignments, decreasing workshop vehicle downtime and shop labor overheads.


Calibrated Idle Vibration Dampening & Signal Stability Optimization: Integrated with a precision-balanced forged crankshaft and solid-state engine control modules, this complete block effectively cancels low-frequency combustion resonance and powertrain shaking. Stabilizing rotational force distribution eliminates sudden engine misfires and reduces erratic cabin rattling, providing a reliable driving workspace and avoiding emission compliance violations.

اشتريتُ قبل ثلاثة أسابيع حشوات زيت متينة لشاحنات أسطولي من شركة HOWO من هذا المتجر المستقل. بصفتي مدير أسطول أدير 22 شاحنة نقل بضائع في لاغوس، كنتُ بحاجة إلى حشوات مطاطية متينة تتحمل درجات الحرارة العالية على الطرق الأفريقية الوعرة. كل حشوة تناسب تمامًا دون أي تسريب للزيت أثناء النقل لمسافات طويلة. استغرقت الشحنة إلى ميناء لاغوس 8 أيام فقط، وكان فريق المبيعات سريع الاستجابة عندما طلبتُ أسعار الجملة.
