On the Forthing SX5, “naturally aspirated” tells you there is no turbo—the 1,590 cc engine breathes using normal atmospheric pressure. “DOHC” means separate overhead camshafts operate the intake and exhaust sides, working with four valves in each cylinder. “Transverse” describes the mounting position: the engine sits across the vehicle rather than lengthwise, which suits its front-wheel-drive configuration.
“Naturally aspirated” bermaksud enjin petrol 1.6L SX5 ini tidak menggunakan turbo atau supercharger; udara masuk melalui tekanan atmosfera biasa. DOHC pula ialah dua aci sesondol di bahagian atas enjin yang mengawal injap masuk dan ekzos, dengan empat injap bagi setiap silinder. Susunan transverse bermakna enjin dipasang melintang dalam ruang enjin, selari dengan konfigurasi pacuan roda hadapan model ini. Enjin empat silinder tersebut menghasilkan 90 kW, 122 PS dan 151 Nm.
These three terms describe how the SX5’s engine breathes, operates its valves and sits under the bonnet. It breathes naturally with no forced induction, uses a DOHC cylinder-head design with four valves per cylinder, and is mounted crosswise. That transverse arrangement goes together with the stated front-wheel-drive system. The unit itself is a 1.6L inline four producing 90 kW and 151 Nm.
自然吸气，意思是这台1.6L汽油引擎没有涡轮或机械增压，靠大气压力把空气吸进引擎。DOHC指双顶置凸轮轴，分别控制进气门和排气门；这台引擎每缸有4个气门。横置引擎则是引擎横向安装在车头，与SX5的前轮驱动布局相配。简单讲，这是一套传统的1.6L直列四缸组合，最大功率90 kW、最大扭矩151 N·m。

Naturally aspirated means the SX5’s 1.6-litre petrol engine draws in air without a turbocharger or supercharger. DOHC refers to two overhead camshafts managing the intake and exhaust valves; this engine has four valves per cylinder. Transverse means the engine is installed sideways across the engine bay, matching the SUV’s front-wheel-drive layout. In short, it is a conventional 1.6L four-cylinder setup rated at 90 kW, 122 PS and 151 Nm.
