This book is a compilation of the inspection and maintenance procedures for A-series EGI engines that use NAPS that conforms to the 1978 emission regulations, compiled as the "A-series Engine Maintenance Procedures Manual [A14-type EGI specification] (for vehicles conforming to the 1978 regulations)".

This book not only describes the inspection and maintenance of NAPS-related devices and EGI devices, but also provides step-by-step instructions for regular inspection and maintenance, general maintenance of the engine on board, and overhaul of the engine itself, so please use it for a wide range of purposes, from daily general maintenance to regular inspection and maintenance.

In particular, this is the first time that an EGI device has been adopted for an A-series engine, and compared to conventional carburetor-equipped engines, the structure, function, inspection, and maintenance procedures have changed significantly.

In order to ensure full customer satisfaction, please read this manual carefully and carry out accurate and prompt service activities.

53年度排出ガス規制適合のA系EGI仕様エンジンは、従来のエンジンを基本に、53年度排出ガス規制に適合するともに、運転性、燃料経済性を向上するためエンジン本体の改良及びEGI 装置ならびに各NAPS装置を装着した改良酸化触谋方式を採用している。

排出ガス清浄化システム"NAPS"及びEGI装置は基本的に次の装置で構成され、53年度排出ガス規制に適合している。

1. エンジン改良(エンジン本体、点火系)

2. EGI装置(吸入空気量検出方式)

3. 排気ガス還流(EGR)装置(負荷比例式〔VVT方式〕)

4. 酸化触媒装置(触媒ペレットの改良)

5. 二次空気導入(EAI)装置

The A-series EGI engine, which complies with the 1978 exhaust gas regulations, is based on the conventional engine, but in addition to complying with the 1978 exhaust gas regulations, it also features an improved oxidation catalytic system with improvements to the engine body and the EGI device and various NAPS devices to improve drivability and fuel economy.

The exhaust gas purification system "NAPS" and EGI device are basically composed of the following devices, and comply with the 1978 exhaust gas regulations.

1. Engine improvements (engine body, ignition system)

2. EGI device (intake air volume detection method)

3. Exhaust gas recirculation (EGR) device (load proportional type [VVT method])

4. Oxidation catalyst device (improvement of catalyst pellets)

5. Secondary air introduction (EAI) device

1－9 エンジン始動上の注意 Cautions for starting the engine

page 18 #English

https://i297.photobucket.com/albums/mm219/ddgonzal/A14E/018.jpg

エンジンの始動方法を問診し、正しい始動方法をユーザーに指導してください。

(1) ハンドブレーキレバーをいっぱいに引き、変速機のシフトレバーをニュートラル位置にする。

(2) アクセルペダルを踏まないで、スターターを回して始動す。

注意:スターターは連続10秒以上回さない。一度回した後は、10秒以上待ってバッテリーを回復させる。

(3) 始動後、暖機運転をする。

注意:

1.始動直後など、エンジンが冷えている場合、無用の空吹しや高回転にしない。

2.暖機されているときでも、停車中に長時間(10分以上)高回転にしない。

(4) エンジン始動後、バッテリーターミナルは絶対に外さない。

Ask the user how to start the engine and instruct them on the correct method.

(1) Pull the handbrake lever all the way in and put the transmission shift lever in neutral.

(2) Turn the starter to start the engine without depressing the accelerator pedal.

Caution: Do not turn the starter for more than 10 seconds continuously. After turning it once, wait 10 seconds or more to allow the battery to recover.

(3) After starting, warm up the engine.

CAUTION:

1. When the engine is cold, such as immediately after starting, do not rev the engine unnecessarily or run it at high speed.

2. Even if the engine has been warmed up, do not run it at high speed for long periods of time (more than 10 minutes) while the vehicle is stopped.

(4) After starting the engine, never disconnect the battery terminals.

This book contains instructions for disassembly, assembly, adjustment, etc. of each device. However, since disassembly and maintenance is regulated by a notification from the Ministry of Transport that "disassembly and maintenance must be carried out by persons certified for automobile disassembly and maintenance," we ask that you always ask a maintenance shop to carry out disassembly and maintenance.
