摘要： An automatic carburetor (20) enrichment system that controls the air-fuel mixture during cold start of an engine (10) having a carburetor including a fuel bowl (22) and an induction passage (23), includes a sensor (50) that provides a signal indicative of an engine temperature at engine start, a fuel line (30) connected between the fuel bowl (22) and the induction passage, a solenoid valve (40) disposed in the fuel line, and a controller (10) that receives the signal and sets a duty cycle of the solenoid valve associated with the engine temperature to increase the air-fuel ratio of the air-fuel mixture at engine start. The automatic carburetor enrichment system reduces cranking time during cold start, eliminates the need for driver input during cold start, prevents engine stalling without assistance from the operator during the warm up phase, provides a simpler, more cost effective and reliable carburetor enrichment, provides self-drowning protection without the use of an electronic idle switch and eliminates the risk of engine drowning when the engine is cranked with the choke ON and the ignition switches OFF.
摘要翻译：一种自动化油器（20）富集系统，其在具有包括燃料碗（22）和进气通道（23）的化油器的发动机（10）的冷启动期间控制空气 - 燃料混合物，包括传感器（50）指示发动机起动时的发动机温度的信号，连接在燃料碗（22）和进气通道之间的燃料管路（30），设置在燃料管路中的电磁阀（40），以及控制器（10）信号并设定与发动机温度相关联的电磁阀的占空比，以增加发动机起动时的空气燃料混合物的空燃比。自动化油器浓缩系统减少冷起动时的启动时间，在冷启动期间不需要驱动器输入，防止发动机在暖机阶段无需操作人员的帮助停机，提供更简单，更具成本效益和更可靠的化油器浓缩，提供自动化在不使用电子怠速开关的情况下进行淹没保护，并消除了发动机在扼流器打开并且点火开关关闭时起动发动机淹没的风险。

摘要： A vehicle, such as a snowmobile, includes an engine with one or more air intakes for receiving air into the engine and an airbox for directing air into the air intakes. The airbox slides to facilitate installation and removal of the airbox from the engine compartment, which thus economizes time and cost both for vehicle assembly and maintenance. The sliding airbox also eliminates the need for a gap between the fuel tank and the airbox, allowing the fuel tank to be moved forward, thus improving mass centralization of the vehicle. The sliding airbox has a rectangular slot which slides onto a rectangular plate on an intake adapter. The intake adapter has a flexible tubular connection for each cylinder of the engine which are secured to each air intake with a hose clamp. The air intake usually includes an air metering device such as a carburetor or throttle body.
